Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
10 because if you minus 170 from 10 it would still be less than 99

Add them together
Answer: 39 hot dogs
M= 3 + half of C , E= 2 × M , C= 12
Step-by-step explanation:
M= 3 + (half of C=12÷2) 6= 9
E=2×9=18
total= 12 + 9 + 18= 39
Answer: Width = 3 and Length = 14
Step-by-step explanation:
Length = 2W + 8
Width = W
Perimeter= 2(width) + 2(length)
34 = 2W + 2(2W +8)
Distribute
34 = 2W + 4W + 16
Combine like terms
34 = 6W + 16
Solve for W
34- 16 = 6W
18 = 6W
W = 3
Substitute 3 in for W in Length equation.
L = 2(3) + 8 = 14
