Im not positive but I think the answer is a.
Answer:
25/28
Step-by-step explanation:
5/4 x 5/7 = 25/28
6 - 1/2z = 2/3
Steps
First, subtract 6 from both sides
6 - 1/2z - 6 = 2/3 - 6
Then, simplify
-1/2z = -16/3
Then, multiply both sides by -2
(-1/2z) (-2) = (-16/3) (-2)
Then, simplify
z = 32/3
Parallelogram area= base * perpendicular height
Assuming that the perpendicular height is 2 ft:
Area of one window = 3.25 * 2 = 6.50 square feet.
Since there are 3 identical parallelograms the Total Area = 3 * 6.5
= 19.5 square feet.
Answer:
7 quarters and 3 dimes
Step-by-step explanation:
x: quarter y: dime
25x + 10y = 205
x+y=10
y = 10-x
25x + 10*(10-x) = 205
25x+100 -10x = 205
15x = 105
x = 7
7 = 10-7 = 3
