4+(((2*2*2)-5)*2)=10
(4+((2*2*2)-5))*2=14
7/8=0.875
7/20=0.35
7/5=1.4
9 29/40 = 9.725
X = pennies
3x = nickels
x-2 = dimes
0.01x + 0.05(3x) + 0.10(x-2) = 1.10
0.01x + 0.15x + 0.10x - 0.20 = 1.10
0.26x-0.20 = 1.10
0.26x = 1.30
x = 1.30 / 0.26 = 5
5 pennies
5-2 = 3 dimes
3*5 = 15 nickels
check: 5 pennies = 0.05, 3 dimes = 0.30, 15 nickels = 0.75
0.75 + 0.30 + 0.05 = 1.10
pennies = 5
nickels = 15
dimes = 3

Answer:
2/3
Step-by-step explanation:
You can see from the diagram that the shaded 1/4 of the second rectangle has the same dimensions as 2 of the 3 shaded parts of the first rectangle.
2/3 of 3/8 is in 1/4
Answer:
x = -3/4
Step-by-step explanation:
Simplify the equation.
5x - 3(3x + 7) = y
5x - 3*3x + 7 *(-3) = y {Distributive rule}
5x - 9x - 21 = y
Combine like terms
-4x - 21 = y
Now, substitute the value of y = -18
-4x - 21 = -18
Add 21 to both sides
-4x = -18 + 21
-4x = 3
Divide both sides by -4
x = -3/4
