Answer:
i dont know if u know the equation for volume but it is length times width times height SO you would multiply 8.25 times 3 times 5
5 times 3 is 15 so u then multiply 8.25 times 15
sorry if u wanted the full answer
Let's say, the number is "a"
thus

cross-multiply and solve for "a"
Simplify both sides of your equation.
Subtract 4 from both sides.
Multiply both sides by 2(-1).
m = -12
Just multiply.
11.76 * 23.5= 276.36
So Mike earned $276.36 last week
7. y=-3/2x+8 (3rd answer choice)
substitute
-4=-3/2(8)+b
-4=-24/2 +b
-4=-12+b
+12 both sides
8=b
so equation would be...
y=-3/2x+8 (3rd answer choice)
8. y=-5x-17 (2nd answer choice)
substitute
-2=-5(-3)+b
-2=15+b
-15 both sides
-17=b
so the equation would be...
y=-5x-17 (2nd answer choice)
check your work by substituting each (x,y) value into the final equations if you want. hope this helps :))
