D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17
hopes it helps:)
5 tenths multuplied by the sum of y and 3 and 3 tenths
Multiply x times -2 then times the second number times -1
Answer:
80
Step-by-step explanation:
5 * 8 * 2
Answer:
the total surface area is 40 + 12 + 15 = 67 square units
Step-by-step explanation:
Refer to the diagram:
the combined area of the top and bottom is 2(5·4) = 40:
the combined area of the ends is 2(1.5·4) = 12; and
the combined area of the front and back is 2( 5 · 1.5) = 15
and so the total surface area is 40 + 12 + 15 = 67 square units
