Answer:
49 and 118
Step-by-step explanation:
Let the two numbers be x and y
x+y = 167
y = 3x-29
Substitute into the first equation
x+ 3x-29 = 167
Combine like terms
4x - 29 = 167
add 29 to each side
4x = 167+29
4x = 196
Divide by 4
4x/4 = 196/4
x = 49
x+y = 167
49+y = 167
y = 167-49
y =118
Answer:
x ≤ 17
Step-by-step explanation:
This is the same as solving an equation, except instead of and equal sign it's an arrow.
We have to evaluate everything in the parenthesis first.
3x - 2 (x + 1) ≤ 15
3x - 2x - 2 ≤ 15
Next, we combine like terms - x's
3x - 2x - 2 ≤ 15
x - 2 ≤ 15
Combine like terms - constants (add 2 to both sides)
x - 2 ≤ 15
<u>x ≤ 17</u>
Answer:5
Step-by-step explanation:
Answer:
MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8
