9514 1404 393
Answer:
54 -6m
Step-by-step explanation:
For values of m < 9, the argument of the absolute value function is less than 0. Then the expression evaluates to ...
-(6m -54) = 54 -6m
140% = $34.30
1$ = 0.245
100% = 0.245 x 100 =$24.50
The cost of the sweater os $24.50
To solve, first add 25 to both sides to get

Then factor to get



There is only one solution, x = 5.
8.4
triangle ABC is 1.2 times bigger than triangle XYZ
10 x 1.2 = 12
5 x 1.2 = 6
so 7 x 1.2 = 8.4
