The second option. Angles 2 and 6 are corresponding angles, and 6 and 7 make a linear pair, so 2 and 7 are supplementary.
The first option doesn’t even mention angle 7, the third option doesn’t mention angle 2, and the last option doesn’t mention 7 either.
Z = -2/3a
divide by -2/3 on both sides
a = z divided by -2/3
a = -3/2z
The answer would be b-5+6
Total of $7.75
13 more quarters than nickels
15 nickels = $0.75
28 quarters = $7.00
28 - 15 = 13 coins
$7.00 + $0.75 = $7.75
She has 15 nickels and 28 quarters.
Commutative property of multiplication is two numbers being multiplied either way,example 1x2 = 2x1.
