Answer:
A
Step-by-step explanation:
8 gallons of regular gas with 10% and 2 gallons with 85%
8 x 10 =80%
2 x 85 =170%
170+80=250%
10 gallons each with 100%, so 10 x 100 =1000%
250% of 1000% = 1/4 or 25% ethanol
Hope this helps!
7x + 4 + 9x = 180
16x = 176
x = 11
9x = 9x11 = 99
7x + 4 = 7(11) + 4 = 77 + 4 = 81
<span>in order to form a rectangular image, each angle needs to be equal 90 degreesn
99 - 9 = 90
81 + 9 = 90
