Answer: x= 1 , y = 7
Step-by-step explanation:
y = -6x + 13 ................. equation 1
y = 3x + 4 ................ equation 2
substitute y = 3x + 4 into equation 1 , then we have
3x + 4 = - 6x + 13
collect the like terms , we have
3x + 6x = 13 - 4
9x = 9
x = 1
substitute x = 1 into equation 2 , we have
y = 3(1) + 4
y = 3 + 4
y = 7
Therefore : x = 1 and y = 7
Answer:
376 inches^2
Step-by-step explanation:
<h3>1. Divide up each type of rectangle </h3>
- 10x6
- 6x8
- 8x10
<h3>2. Find the area of each rectangle</h3>
- 10x6=60
- 6x8=48
- 8x10=80
<h3>3. Multiply each rectangle by two to get the opposite one</h3>
- 60x2=120
- 48x2=96
- 80x2=160
<h3>4. Add them together</h3>
120+96+160=376
The surface area is 376 inches^2
Step-by-step explanation:
a-2=3+6a/3
By cross multiply
3(a-2)=3+6a
3a-6=3+6a
-6-3=6a-3a
-9=3a
a=-3
