Answer:
b = -1
Step-by-step explanation:
3(-4b+1) = 15
multiply: -12b + 3 = 15
subtract 3 from 15: -12b = 12
divide: b = -1

How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it
Answer:
x = 7
Step-by-step explanation:
How to solve your question
Your question is 13 + 3 − 8x + 6 = 1 − 5x
13 +3 - 8x + 6 = 1 - 5x
13 + 3 − 8x + 6 = 1 − 5x
Solve
Add the numbers
13 + 3 − 8x + 6 = 1 − 5x
22 − 8x = 1 − 5x
Rearrange terms
22 − 8x = 1 − 5x
−8x + 22 = 1 − 5x
Subtract 22 from both sides of the equation
−8x + 22 −22 = −5x + 1 − 22
Simplify
Subtract the numbers
−8x = -5x + 1 -22
-8x = -5x -21
Add 5x to both sides of the equation
-8x + 5x = -5x -21 + 5x
Simplify
Combine like terms
-3x = -21
Divide both sides of the equation by the same term
(-3x)/3 = (-21)/3
Simplify
Cancel terms that are in both the numerator and denominator
x = (-21)/(-3)
Divide the numbers

Andrew 720 seconds take shower and 420 seconds eating breakfast how many minutes does it take Andrew take a shower and eat breakfast
Answer:
Total time = 19 minutes.
Step-by-step explanation:
Given the following data;
Time to shower = 720 seconds
Time to eat breakfast = 420 seconds
To find the total time in minutes;
Total time = 720 + 420
Total time = 1140 seconds
We know that 60 seconds equals a minute.
Total time = 1140/60
Total time = 19 minutes.
Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..

4(x + 1)
(4 x + 5)
4(x - 1)
(5 - 4x)
4(x - (-1))
(4 x + 5)
4 (X + (-1))
(4 x + 5)
4 (x + 1)
(5 - 4x)
Answer:
4(x + 1) and 4(x - (-1))
Step-by-step explanation:
4(-1 + 1) = 4(0) = 0
(4 (-1) + 5) = -4 +5 = -1
4(-1 - 1) = 4(-2) = -8
(5 - 4(-1)) = 5 + 4 = 9
4(-1 - (-1)) = 4(0) = 0
4 (-1 + (-1)) = 4(-2) = 8

What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.
Question 1
Find the measure of each angle indicated.
Answer:
90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
x + 70 =120 {Exterior angle theorem}
x = 120 - 70
x = 50
y = x {Vertically opposite angles}
y = 50
z + 50 + 40 = 180 {Angle sum property}
z + 90 = 180
z = 180 - 90
z = 90
There are 18 girls in Mr. Brimley's math class. If 40% of the students are girls, what is the best estimation for the number of boys in the class?
Answer:
30
Step-by-step explanation:
This is an easy one.
So, we know that 40% of the class is girls. We would need to use the other 60% as 60% of the class is boys and we would need to divide.
18/0.6=30
Therefore your answer is 30.
Hope this helps.
Answer:
20
Step-by-step explanation:
It is 40 percent ( given)
18/2=9
9×5=40 (100%)
Girls- 18( given)
Boys- 40-18=22

What is the value of angle 2?
1//2
+
66°
Please helpp
Answer:
The value of angle 2 is 114 degrees
Step-by-step explanation:
We start with 180 degrees, since it is a Line.
To fine the other degree, subtract 66 from 180, which is 114
Angle 2 is 114 because of the theory of interior alternate angles are congruent. Angle 1 is 66 degrees because of the same reason.

Ms. Rios mowed
2
7
of her lawn. Her son mowed
1
4
of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:
Ms Rios mowed more
Step-by-step explanation:
I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%
Now if her son mowed 14% and it was still at 100% it would be at 86%
So in the end Ms Rios mowed more of her lawn
