It is equal to 7.5
Because every side times 2.5 will give you the similar side.
55*3=165
165-54.3=110.7
110.7-56.1=54.6
54.6=answer
Answer: 9 is A
Step-by-step explanation:
area of triangle= 1/2 bh
1/2 of 8 is 4
4x10= 40
40x3= 120
1/2 of 8=4
4x6.9= 27.6
120+27.6=147.6 sq. m
X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
