hi how do add in math
Answer: just put whatever numbers you have together and then see what the both add up to like what number they make
Answer:
Hi! I'm going to try to explain this in the best way possible. Basically, when adding in math, we're taking 2 or more numbers, and combining their values to make a different number. For example, if we have 1 and 1, which would be represented as 1 + 1, that would be the value of 1 added to the value of 1, which is 2. You can also do this on your fingers. Since we have 10 fingers, you would count 1 of them and another 1 of them to get 2 fingers! If we try a different problem, such as 2 + 1, that would be the sum of the value of 2 and the value of 1. When counting on your fingers, that would be 2 fingers and another finger. That's 3 fingers. 2 added to 1 is 3! I hope this makes some sort of sense! Tell me if you need more clarification :)

An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece. What is the length of the shorter piece of wire? Enter your answer as a number only (no letters or symbols). Do not include units.
The length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.
Given to us
An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece.
What are the two equal parts of the wire?We know that the length of the wire is 49 m, therefore, to cut the wire in two equal parts divide the total length of the wire by two,
[tex]\dfrac{49}{2} = 24.5[/tex]
Thus, the length of each side will be 24.5.
What is the length of the shorter piece of wire?Since we need to cut the wire such that one side of the wire is 5 less than the other, we already know the length of the equal sides deduct (5/2) from both sides to create a difference between the length of the wire.
Length of the shorter wire = 24.5 -2.5 = 22.5
Length of the longer wire = 22.5 + 5 = 27.5
Hence, the length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

Step-by-step explanation:
Use simplification into substitution
[tex]\frac{a}{3} =1+\frac{2}{b}[/tex]
[tex]a=3(1+\frac{2}{b})[/tex]
[tex]a=3+\frac{6}{b}[/tex]
We can now plug this value of a into the second equation.
[tex]\frac{3+\frac{6}{b} }{4} +\frac{3}{b} =3[/tex]
Get rid of fractions in the numerators and/or denominators
[tex]\frac{3b+6}{4b} +\frac{3}{b} =3[/tex]
Then we can match the denominators
[tex]\frac{3b+6}{4b} +\frac{12}{4b} =3[/tex]
Combine
[tex]\frac{3b+18}{4b} =3[/tex]
Divide both sides by three
[tex]\frac{b+6}{4b} =1[/tex]
Get rid of fractions
[tex]b+6=4b[/tex]
Single out b
[tex]6=3b[/tex]
[tex]b=2[/tex]
Now we can plug it into the equation
[tex]\frac{a}{3} -\frac{2}{2} =1[/tex]
[tex]\frac{a}{3} =2[/tex]
[tex]a=6[/tex]
Now we can check it;

3. When you multiply a number by a fraction, will the product be larger or smaller than the largest factor?
Answer: The identity property of multiplication tells us that a number x 1 has a product equal to the number (itself).
Step-by-step explanation:
For example, 4 x 1 = 4. So when we multiply by a fraction that is less than 1, our product has to be less than the number we are multiplying the fraction by.
The result of multiplying a number by a fraction often becomes either smaller, larger or equal to the largest factor.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
When you multiply a number by a fraction, the product will generally be smaller than the largest factor. This is because a fraction represents a part of a whole, and is therefore less than 1. For example, if you multiply the number 10 by the fraction 1/2, the product will be 5, which is smaller than 10.
However, it is possible for the product to be larger than the largest factor if the fraction is greater than 1. For example, if you multiply the number 10 by the fraction 3/2, the product will be 15, which is larger than 10.
It is also possible for the product to be equal to the largest factor if the fraction is equal to 1. For example, if you multiply the number 10 by the fraction 1/1, the product will be 10, which is equal to 10.
Thus, often, when a fraction is multiplied by a number, the result is either lower, greater, or equal to the greatest factor.

Jennifer's bank account is modeled by the following equation where equals the number of months and y equals the balance: y = 24x + 50
Answer:
50
Step-by-step explanation:
Jennifer's bank account started with 50 because that's the y-intercept in the equation (y= mx+b). b is always what you start with.
Answer:
Part A: 50 dollars
Part B: y=28x+60
Part C: Jennifer is wrong
Part D: William will a greater balance
Step-by-step explanation:
A: Jennifer's equation is represented in slope-intercept form, or y=mx+b, where m is how much she earns per month, and b is her initial value, therefore, her initial value is 50.
B: Using the table, we can use y=mx+b as a formula. We first find the slope by doing 88-60=28. Then we see that at month 0, his initial value is 60, leaving us with y=28x+60.
C: Using the slopes for both equations, we see the William's balance is growing by 28, 3 more than Jennifer's 25.
D: We can plug in 12 for x for both equations. 25(12) + 50 = 338 28(12) + 60 = 396

Mary used the equation 292 = 5h + 192 to determine her
salary at the restaurant last week. Which situation does this
equation best represent?
Answer:
Mary worked 10 hours last week and received $192 in tips for a total income of $292.
Step-by-step explanation:
I don't see any answer options. The best I can assume is that h stands for hours. If so, Mary makes $5/hour. The 1932 doesn't have units, but I'll assume it is $. The $192, I'll guess, is her average weekly tip income. The difference between 292 and 192 is $100, so that would mean Mary worked 20 hours last week. Her tip income is almost double her salary.
A florist charges $5.00 for delivery plus an additional $1.00 per mile from the flower shop. The florist pays the delivery driver $0.75 per mile and $3.50 for gas per
delivery. If x is the number of miles a delivery location is from the flower shop, what expression models the amount of money the florist earns for each delivery?
Find the function that models the amount of money the florist earns for each delivery.
The florists charges and delivery are illustrations of linear functions
The amount made by the florist per delivery is y = 1.5 + 0.25x
How to determine the functionsFor the charges, we have:
Delivery = $5.00Rate = $1.00 per mileRepresent the cost with y, and the number of miles with x.
The function that represents the amount the florist made is:
y = 5 + x
For the delivery, we have:
Gas = $3.50Rate = $0.75 per mileThe function that represents the delivery is:
y = 3.5 + 0.75x
The amount made by the florist per delivery is then calculated as:
y = 5 - 3.5 + x - 0.75x
y = 1.5 + 0.25x

TrigonometryTrigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Right angle triangleIt is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
Given
Sin A = 5 ÷ 13 and Tan B = -√3.
To findThe value of tan(A - B).
How to find the value of tan(A - B)?The angle A will be,
[tex]\begin{aligned} \rm sin A &= \dfrac{5}{13}\\\\\rm A &= \rm sin^{-1} \dfrac{5}{13}\\\\\rm A &= 22.62^o\\\\\end{aligned}\\But\ for\ the\ \dfrac{\pi}{2} < A < \pi\\\\A = 22.62^o + 90^o\\\\A = 112.62^o[/tex]
Similarly for angle B,
[tex]\begin{aligned} \rm tan B &= -\sqrt{3} \\\\\rm B &= \rm tan^{-1} -\sqrt{3} \\\\\rm B &= -60^o\\\\\end{aligned}\\\rm But\ for\ the\ \dfrac{\pi}{2} < B < \pi\\\\B = -60^o + 180^o\\\\B = 120^o[/tex]
Then tan (A - B) will be
Tan(A - B) = tan(112.62 - 120)
Tan(A - B) = tan(-7.38)
Tan(A - B) = -0.1295
Thus, the value of Tan(A - B) is -0.1295.
