A. 1
b. 1
c. 1
d. 1/2
2. 1/2
3. Yes they did break it because there are 3 wholes.
2(x - 4) + 7(x + 2)
mutiply the first bracket by 2
(2)(x)=2x
(2)(-4)= -8
mutiply the second bracket by 7
(7)(x)=7x
(7)(2)= 14x
2x-8+7x+14
2x+7x-8+14 ( combine like terms)
Answer:
9x+6 or 6+9x
Answer:
20.599
Step-by-step explanation:
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
Answer:
z=116 (opposite angles are equal)
y=180-(116+27)=37(angles in a triangle sum up to 180)
x:
(z) + (27+x) =180(interior angles on same side are supplementary
116 + 27+ x =180
x= 37
