Answer:
The money he can save by buying them at Big 5 is $76.80.
Step-by-step explanation:
Given:
Footballs sell for $27.99 each at Sporting Goods.
Footballs sell for $21.59 each at Big 5.
The coach buys a dozen footballs.
Now, to find the amount he save by buying them at Big 5.
So, first we find the cost of footballs at Sporting Goods and at Big 5.
1 Dozen = 12 pieces.
Thus, the cost of footballs at Sporting Goods =
And, the cost of footballs at Big 5 =
Now, to get the amount coach can save by buying them at Big 5, we subtract both the cost as the cost of Sporting Goods is more than the Cost of Big 5:
The amount coach can save by buying them at Big 5 =
Therefore, the amount he can save by buying them at Big 5 is $76.80.
Substitute the values given.
-2-3(2) then solve
Your answer should be -8
The greatest common factor of 10 and 20 is 10.
Answer:
x = 0.75
Step-by-step explanation:
Simplifying
(7x + -5) + -1(3x + -2) = 0
Reorder the terms:
(-5 + 7x) + -1(3x + -2) = 0
Remove parenthesis around (-5 + 7x)
-5 + 7x + -1(3x + -2) = 0
Reorder the terms:
-5 + 7x + -1(-2 + 3x) = 0
-5 + 7x + (-2 * -1 + 3x * -1) = 0
-5 + 7x + (2 + -3x) = 0
Reorder the terms:
-5 + 2 + 7x + -3x = 0
Combine like terms: -5 + 2 = -3
-3 + 7x + -3x = 0
Combine like terms: 7x + -3x = 4x
-3 + 4x = 0
Solving
-3 + 4x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 4x = 0 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = 0 + 3
4x = 0 + 3
Combine like terms: 0 + 3 = 3
4x = 3
Divide each side by '4'.
x = 0.75
Simplifying
x = 0.75
