Answer:
-70 so A
Step-by-step explanation:
Answer:
D) 70
Step-by-step explanation:
Here is the correct mathematical way of find a distance between two points on the number line.
Take the absolute value of the difference of their coordinates.
If the points on a number line correspond to coordinates a and b, the distance between the points is
|a - b|
Your problem:
|a - b| = |-57 - 13| = |-70| = 70
The distance is 70.
Answer: D) 70

Christian burns 4 1/2 calories in 2/3 if a minutes riding his bike. HOW MANY CALORIES WILL CHRISTAN BURN IN 1 MINUTE OF BIKE RIDING? SELECT THE CORRECT ANSWER.
Answer:
The answer is 6.75 calories or [tex]6 \frac{3}{4}[/tex]
Step-by-step explanation:
First, we need to find out how many calories per 1/3 minute.
4 1/2 divided by 2 = 2 1/4 or 2.25
2 1/4 or 2.25 x 3 = [tex]6 \frac{3}{4}[/tex] or 6.75 calories

3×_5=16 and 3×=21
the first equation is a true statement for a certain value of x.
can you explain why the second equation must also be true for the same value of x?
Understanding:
First, let's try simplifying the first equation as much as we can. As you know, you can add, subtract, multiply, divide, etc on both sides of the equation and it will remain the same value. To simplify [tex]3x-5=16[/tex] we can simply add 5 to both sides to cancel the -5 on the left-hand side. That will give us [tex]3x-5 +5=16+5[/tex], notice we added the 5 to both sides. The +5 cancels -5 and 16+5 is 21, which evaluates to [tex]3x=21[/tex]. And this equation looks familiar, it's our second equation actually. That's why both equations are the same, and in that x value that makes the first equation true, it will also do the same for the second equation. If you want to actually find the value of x which makes the equation true, you can simply divide the 21 on the right-side by 3 to make x coefficient equal to 1, [tex]\frac{3x}{3} =\frac{21}{3}[/tex], and that gives us, [tex]x=7[/tex]. When x is 7 both equations are true.
Answer:
We conclude that the second equation must also be true for the same value of x because the value x = 7 satisfies the 2nd equation too.
Step-by-step explanation:
Given the first equation
[tex]3x-5=16[/tex]
Add 5 to both sides
[tex]3x-5+5=16+5[/tex]
simplify
[tex]3x=21[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{21}{3}[/tex]
simplify
[tex]x=7[/tex]
Thus, x = 7 is a value that satisfies the first equation.
Now, put x = 7 in the 2nd question to check whether x = 7 satisfies the equation or not.
3x = 21
3(7) = 21 ∵ x = 7
21 = 21
Thus, x = 7 also satisfies the 2nd equation.
Therefore, we conclude that the second equation must also be true for the same value of x because the value x = 7 satisfies the 2nd equation too.
What is -12.25 / (1.4)?
A. -13.65
B. -8.75
C. 8.75
D. 13.65
Answer:-8.75
Step-by-step explanation:
Answer:
C. -8.75
Step-by-step explanation:
Ultimately, you are dividing a negative number by a positive number which makes the answer negative. The only way the answer can be positive if it's dividing by two negatives or two positives. You can also assume that since the divider is greater than 1, it is usually less than the first number for this statement which makes your answer -8.75.

Two trains leave the station at the same time, one traveling due east, the other due west. After 46 minutes, they are 140 miles apart. If one train's speed is 20 mph more than the other train's, what are the speeds of the two trains.
Train A speed = x + 20
Train B = x
We know that 46 minutes is 23/30 of an hour.

Answer/Step-by-step explanation:
The following steps to solve equation given by join are shown below including the property of numbers applied for each reasons:
4(2a + 3) = -3(a - 1) + 31 - 11a ----› Given
Apply the distributive property to open the parentheses
4*2a + 4*3 = -3*a -3*-1 + 31 - 11a
8a + 12 = -3a + 3 + 31 - 11a ----› Distributive property
Combine like terms together
8a + 12 = 3 + 31 -3a - 11a
8a + 12 = 34 - 14a ---› Combining like terms
Add 14a to both sides
8a + 12 + 14a = 34 - 14a + 14a
22a + 12 = 34 ----› Addition property
Subtract 12 from both sides
22a + 12 - 12 = 34 - 12
22a = 22 ----› subtraction property of equality
Divide both sides by 22
22a/22 = 22/22
a = 1 ----› Division property of Equality

An angle measures 29.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
104.6 deg, 75.4 deg
Step-by-step explanation:
One angle measures x.
The other angle measures 29.2 deg less than x, so it measures x - 29.2.
They are supplementary angles, so the sum of their measures is 180 deg.
x + x - 29.2 = 180
2x - 29.2 = 180
2x = 209.2
x = 104.6
x - 29.2 = 75.4
Answer: 104.6 deg, 75.4 deg

What pair of points have a slope of -3/5
Answer:
(5,0) and (0,3) have a slope of -3/5
Step-by-step explanation:
Here, we want to state a pair of points that have a slope of -3/5
Mathematically, we can have the slope of a straight line calculated as;
m = y2-y1/(x2-x1)
This could give points like (5,0) and (0,3)

Yuson must complete 30 hours of community service. She does 2 hours each day. Which linear equation represents the hours Yuson left after x days?
Will mark brainliest if correct
Answer:
y = 30 - 2x
Step-by-step explanation:
She must complete 30 hours, so we start at 30 hours.
Each day, she has 2 less to do after she does her service hours.
So if x = # of days, then that is -2x
Put that together,
y = 30 - 2x

An art teacher had 57 grams of blue clay. She combined it with 31 grams of yellow clay to make green clay. She let students use the green clay during the week. At the end of the week, the remaining green clay weighed 18 grams.
Step-by-step explanation:
Amount of green clay at the start = 57g + 31g = 88g.
Amouny of green clay used = 88g - 18g = 70g.
Hence 70g of green clay was used during the week.
John played 8 games of basketball this season. In his first 2 games, he averaged 5 more points scored than he did in the next 6 games. If he scored 90 points during the 8 game stretch, then how many points did he score in the first two games of the season, added together?
HELP FASTTTT I need the work for this problem
Answer:
30Step-by-step explanation:
Let the average score in the last 6 games be x, then average score in first 2 games is x + 5
Considering the total score of 90 solve for x the equation:
2(x + 5) + 6x = 902x + 10 + 6x = 908x = 80x = 10In the first 2 games John's score was:
2(10 + 5) = 30for f(x) =4x+1 g(x)=x²-5, find (f•g)(x)
Step-by-step explanation:
The composite function (f o g)(x)
= f(x² - 5)
= 4(x² - 5) + 1
= 4x² - 19.
4x² - 19
