Answer:
<h3>x=9</h3><h3>y=12</h3>
Step-by-step explanation:
Plug x as 2y-15 in the first equation and solve for y.
-5(2y-15)+4y=3
-10y+75+4y=3
-6y+75=3
-6y=-72
<em>y=12</em>
Plug y as 12 in the second equation and solve for x.
x=2(12)-15
x=24-15
<em>x=9</em>
Answer:
Step-by-step explanation:
A recipe for a pan of brownies requires 1 ½ cups of milk. Converting the 1 1/2 to improper fraction, it becomes 3/2 cups of milk
The recipe also requires 2/3 cups of sugar
It also requires 1 1/5 cups of oil. Converting to improper fraction, it becomes 6/5 cups of sugar
Total number of cups of ingredients in the mixing Bowl will be sum of the amount if milk, sugar and oil. It becomes
3/2 + 2/3 + 6/5 = (45 + 20 + 36)/30
= 101/30 cups of ingredients
A = ((B+b)*h)/2
A = ((6+4)*3)/2
A = 15
