Simple form of the equation y= ax+b
y= (1/7)x + 12
come from 2 equation :
22= 70 a + b
27= 105 a + b
Answer:
B
Step-by-step explanation:
He used 16 oz of dark chocolate........he used 2/5 to make frosting....meaning he used 3/5 for the brownies.
2/5(16) = 32/5 = 6.4 oz for frosting
3/5(16) = 48/5 = 9.6 oz for the brownies
Therefore, he used (9.6 - 6.4) = 3.2 more oz in the brownies then in the frosting
<span>twice the sum of a number and seven is 8
2(x+7)=8</span>
-3/5 because you multiply 9/10 by -2/3
