Answer:
6) x=5
7)x=6
8)x=10
9)x=12
Step-by-step explanation:
6) 3x-5=10. 7) 36=4x+12. 8) 3(x+2)=36
+5 +5. - 12. - 12. 3x + 6=36
3x = 15. 24 = 4x. - 6. -6
÷3. ÷3. ÷4. ÷4. 3x=30
x=5. 6 = x. x = 10
9) 7(2x-15)=63
14x - 105=63
+105. +105
14x = 168
÷14. ÷14
x=12
Answer:
15 Pancakes
Step-by-step explanation:
In order to solve, you need to divide 5 and 1/3. 5/1*3/1=15
Answer:
Step-by-step explanation:
<u>Step 1</u>:-
Given problem is [(x + 1)(x - 1)]^2
by using formula in side square bracket is
![[x^{2} -1]^{2}](https://tex.z-dn.net/?f=%5Bx%5E%7B2%7D%20-1%5D%5E%7B2%7D)
<u>Step 2</u>:- again we will use formula
^{2} = (x^{2}) ^{2} -2 x^{2} (1)+1^{2}](https://tex.z-dn.net/?f=%5Btex%5D%28x%5E2-1%29%5E%7B2%7D%20%3D%20%28x%5E%7B2%7D%29%20%5E%7B2%7D%20-2%20x%5E%7B2%7D%20%20%281%29%2B1%5E%7B2%7D)

on simplification we get
<u>Final answer:-</u>

Answer:
linear
Step-by-step explanation:
to be a linear equation it needs to have consistent rate of change for x and y. its constant for x at +4 but not for y at +16 +8 and +16
