- 3(x - 7) + 2 = 20 I need help to solve it
Answers
X=1
-3(x-7)+2=20
-3x + 21 + 2 = 20
-3x + 23 = 20
-23. -23
-3x=-3
Divide by -3
X=1
Answer:
x=1
Step-by-step explanation:
First you will distribute it
U basically multiply the 3 by the X and the 7 here
-3 x (x = -3x And the 7 becomes a 21
Then you add the 2
21 + 2 = 23
Then you add the -3
-3x + 23 =20
Then using the equation above you subtract 23 from both sides
(-3 + 23) - 23 = 20 - 23
Then you simplify it
-3x = -3
Then you divide them using the same term
-3
÷ -3
Then you simplfy it and you get
x=1
Solve for b. b + 2 = 4.6

Answers
Answer:
b=2.6
Step-by-step explanation:
b+2=4.6
Subtract both sides by 2 to isolate b
b+2-2=4.6-2
b=2.6

For each fraction, select the most appropriate estimate. 36 40 choose.. 1 3 choose.. 70 100 choose.. 1 8 choose.. Options: Closest to 0 Closest to one half Closest to 1
Answers
Answer:
Convert each fraction to its percentage form:
= 36 / 40
= 90%
= 1/3
= 33.3%
= 70/100
= 70%
= 1 / 8
= 12.5%
Looking at the percentages:
= 36 / 40 is closest to 1.
= 1/3 and 70/100 are closest to one half which is 50%
= 1/8 is closest to 0.

B comes out to xx=2 which could be x=1.
C comes out to xx=-16 which could mean that x equals -8.

An angle measures 56° more than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
62,118
Step-by-step explanation:
Let one angle = x
So, other angle = x +56
x +x +56 = 180 {Combine like terms}
2x + 5 6 = 180 {Subtract 56 form both sides}
2x = 180 - 56
2x = 124 {Divide both sides by 2}
x = 124/2
x = 62
Other angle = 62 + 56 = 118

Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10. Im not sure if this is the nearest cent but here are the steps to find the nearest cent.
