Hello!
Judging by the question you have provided I have come up with an equation to find the answer!
The equation is as follows: $0.25(Amount of quarters)(40) + $0.10 (Amount of dimes)(50) + $0.05 (Amount of nickels)(40) = Total Money!
First you want to input the amount of each coin(s) that you have.
Your new equation should be
$0.25 (4)(40) + $0.10 (3)(50) + $0.05 (6)(40).
If you solve the equation you should get $67.00 as your total!
Hope this helped!

Hello there!
So there are two separate problems: 9 * (11-4) and 3 * (11-4). To find the value for each expression, use order of operations. We'll solve what's in the parenthesis before multiplying that value by the other number. 11-4 is 7. 7 * 9 is 63. 11-4 is 7. 7 * 3 is 21. You can divide 63 by 21 to get 3. This means that 9 * (11 - 4) is three times as much as 3 *(11 - 4). Even just by looking at the problem, the expression in the parenthesis is the same thing, but the front numbers are different. 9 is three times as much as 3. The answer is A.
Answer:
x>1
Step-by-step explanation:
move the constant to the right side and change its sign 7x>10-3
Then subtract the numbers 7x>7
Then divide the inequality by 7 from for both sides.
x>1
Answer:
Since we know what y is, it is 3x+9, we can substitute 3x+9 in for y in the first equation
4x+5y=7
Substitute 3x+9 in
4x+5(3x+9)=7
Distribute the 5
4x+ 5*3x +5*9=7
(4x+15x)+45=7
Combine like terms
19x=-38
Divide both sides by 19
x= -2
Now we know x, and have to find y. Substitute -2 in for x in either of the equations
y=3x+9
y=3(-2)+9
y=-6+9
y=3
