Find the solution to the systems of equations using the elimination method. 3x + 5y = 2 5x + 8y = 4
1 answer:
Answer:
Step-by-step explanation:
3x + 5y = 2 (times 5) 15x + 25y = 10
5x + 8y = 4 (times 3) 15x + 24y = 12
.
15x + 25y = 10
<u>15x + 24y = 12 </u> <u> </u>
y = -2
.
Substitute the value of y to one of equations
3x + 5y = 2
3x + 5(-2) = 2
3x - 10 = 2
3x = 2 + 10
3x = 12
x = 4

Answer:
246 in^2
Step-by-step explanation:
Given data
Length= 8 in
Width= 3 in
Height= 9 in
SA= 2( lw + wh + hl)
substitute
SA= 2(8*3+ 3*9+ 9*8)
SA= 2(24+ 27+72)
SA= 2(123)
SA= 246 in^2
Hence the SA is 246 in^2
