Answer:
Step-by-step explanation:
a + c = 92.....c = 92 - a
8a + 5c = 688
8a + 5(92 - a) = 688
8a + 460 - 5a = 688
3a = 688 - 460
3a = 228
a= 228/3
a = 76 <==== adults
a + c = 92
76 + c = 92
c = 92 - 76
c = 16 <=== children
Answer:
Your answer will be x=2
Step-by-step explanation:
Five plus 6 times a number is equal to 21 minus 2 times the number
Your equation is this:
5+6x=21-2x
Subtract 6x from both sides
5+6x-6x=21-2x-6x
5=21-8x
subtract 21 on both sides
5-21=21-21-8x
-16=-8x Divide -8 on both sides
2=x

The correct statement is D.
Step-by-step explanation:
Given,
For backyard
Length = 5x-2
Width = 2x+4
For house
Length = 5x-2
Width = 4x-12
For driveway
Length = x+10
Width = 4x-12
To find the correct statement.
Formula
The area of a rectangle = Length × Width
So,
The area of the house and the driveway = (5x-2)(4x-12) + (x+10)(4x-12)
= (4x-12)(5x-2+x+10)
= (4x-12)(6x+8)
=
=
So, the correct statement is D
