How do I simplify linear expressions.
Answer:
Step-by-step explanation:
Simplify both sides of the equation and combine all same-side-like terms.
Combine opposite-side like terms to obtain the variable term on one side of the equal sign and the constant term on the other.
Divide or multiply as needed to isolate the variable.
Then double-check the answer.

12. A rectangle has a height of 1 and 3/4 feet. The
area is 5 and 5/6square feet. What is its length?
Answer:
L = 3 1/3 feet
Step-by-step explanation:
A = length × width
now let's change all the mixed numbers into improper fractions:
35/6 = 7/4 × L
we must divide each side by 7/4
35/6 ÷ 7/4 is the same as 35/6 × 4/7 = 20/6 or 3 1/3

Jen bought 5 equal-priced items. If the total tax for all the
items was $2 and she paid a total of $42, how much did
each item cost?
Write and solve an equation to answer the question, and then identify the
statement that is not true.
A. x represents the cost of each item.
B. The equation is 5x + 2 = 42.
C. The first step in solving the equation is to subtract 2 from each
side.
O D. The solution is x = 5.
prove that
2tan(π/4-A)÷1+tan²(π/4-A) = cos2A
Recall the following identities,
• 1 + tan²(x) = sec²(x)
• sin(2x) = 2 sin(x) cos(x)
• sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
as well as the following properties of sine and cosine,
• cos(-x) = cos(x)
• sin(-x) = -sin(x)
Then we have
2 tan(π/4 - A) / (1 + tan²(π/4 - A)) = 2 tan(π/4 - A) / sec²(π/4 - A)
… = 2 tan(π/4 - A) cos²(π/4 - A)
… = 2 (sin(π/4 - A) / cos(π/4 - A)) cos²(π/4 - A)
… = 2 sin(π/4 - A) cos(π/4 - A)
… = sin(2 (π/4 - A))
… = sin(π/2 - 2A)
… = sin(π/2) cos(-2A) + cos(π/2) sin(-2A)
… = cos(2A)
as required.
0.175 as a percentage
Answer: 17.5%
To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.175 × 100 = 17.5% (answer).
➥ The ease way:
1) Move the decimal point two places to the right: 0.175 → 1.75 → 17.5.
2) Add a % sign: 17.5%
Answer: 17.5%
Answer:
0.175x 100= 17.5

HELP PLS I DONT UNDERSTAND QUESTION IN PIC
Which of these numbers is irrational?
A. 12
B. -4.2
C. 1/42
D. 4.2
Answer:
A: 12
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction. (Irrational means not rational).
Therefore, we can immediately discount C as 1/42 is a rational number by inspection.
[tex]4.2=\frac{4.2}{1} =\frac{4.2}{1} \times \frac{10}{10} =\frac{42}{10}=\frac{21}{5}[/tex] so similarly -4.2 = -21/5
So as B and D can also be written as rationals, they are not irrational.
Therefore, A is irrational.

Step-by-step explanation:
Steps for adding fractions
Find the least common denominator or LCM of the two denominators:
LCM of 14 and 7 is 14
Next, find the equivalent fraction of both fractional numbers with denominator 14
For the 1st fraction, since 14 × 1 = 14,
3/14 = 3 × 1/14 × 1 = 3/14
Likewise, for the 2nd fraction, since 7 × 2 = 14,
1/7 = 1 × 2/7 × 2 = 2/14
Add the two like fractions:
3/14 + 2/14 = 3 + 2/14 = 5/14
So, 3/14 + 1/7 = 5/14

what does cos mean in math?
Answer:
cosine
Step-by-step explanation:
"cos" is an abbreviation for "cosine," the name of the trig function that relates the hypotenuse of a right triangle to the length of the side adjacent to the angle of interest.
For an angle measured in radians, the value of the cosine of the angle is defined by the power series shown in the second attachment. Any scientific or graphing calculator can evaluate this function. Generally, best accuracy from a calculator is obtained for angles between -2π and +2π radians, or ±360°. Calculators generally can use angles expressed in degrees or radians, so care is required to make sure the calculator mode matches the units you are using. (Spreadsheet functions typically require angles to be in radians.)
The cosine function is periodic, with a period of 2π radians. Its value for x=0 is 1. A graph of the cosine and sine (abbreviated "sin") functions is shown in the third attachment. Each is a horizontal shift of the other.
__
The three primary trig functions relate pairs of sides of a right triangle to one of the acute angles. The relationship between trig functions and sides is summarized in the mnemonic SOH CAH TOA. The first attachment shows what that means.

What is -5x squared - 2x squared?
If you're talking about (-5x^2 - 2x^2), It'd be -7x^2.
If you're talking about (-5x)^2 - (2x)^2, it'd be 21x^2.
I assume you're talking about the first one, though.

Please help me
Answer:
y=2x-7, the slope is two and the y-intercept is -7
Step-by-step explanation:
2(x-3)=y+1
Distributive prop.
2x-6=y+1
Changing into slope-intercept form
y+1=2x-6
Subtract both sides by one
y=2x-7
The slope is two and the y-intercept is -7

Nardia plots points showing equivalent ratios on the coordinate plane below. Mc018-1. Jpg Which ordered pair would represent a ratio that is equivalent to those shown? (6, 12) (9, 6) (8, 12) (12, 8).
The ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)
Ratio and proportionsFrom the given diagram, we can create two coordinate points which are (2, 3) and (4, 6)
We need to determine the ordered pair would represent a ratio that is equivalent.
Multiplying the coordinate by a scale factor of 4 will give
A(2, 3) = A'(4(2), 4(3)) = (8, 12)
Hence the ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)

An ambulance travels at 40 mph and can follow a 20-mile route making no stops to get to the hospital. A helicopter travels at one mile per minute, and the air route is 15 miles to get to the same hospital. However, the helicopter takes three minutes for takeoff and three minutes for landing. How many fewer minutes does it take for the helicopter to complete its trip (takeoff, flight and landing) than for the ambulance to complete its trip
Answer:
9
Step-by-step explanation:
The time required by the ambulance is ...
time = distance/speed
time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes
The time required by the helicopter is ...
trip time = takeoff time + route time + landing time
= (3 min) + (15 mi)/(1 mi/min) +(3 min) = (3 + 15 + 3) min = 21 min
The difference in times is ...
(30 min) -(21 min) = 9 min
The helicopter takes 9 fewer minutes for the trip.
