18) Let x be the number of coins in the pouch:
3x + 3 = 9; subtract 3 from each side:
3x + - 3 = 9 -3
3x = 6 . Now divide both side by 3:
x = 2 (in each pouch we have 2 coins)
19) SAME logic:
4x + 1 = 2x + 7; subtract 1 from each side:
4x + 1 - 1 = 2x + 7 - 1
4x = 2x + 6; now subtract 2x from each side:
4x - 2x = 2x + 6 - 2x
2x = 6 and x = 3 (each pouch contains 3 coins)
She will be $1.40 under budget.
8% = 8/100 = 0.08
Adding this to 100% of the price of the shoes, we get 108% = 108/100 = 1.08.
We multiply the price of the shoes by this:
45*1.08 = 48.60
Subtract this from 50:
50 - 48.60 = 1.40
Answer:
768 cubic feet
Step-by-step explanation:
16 * 24 = 384
384 * 3 for the depth of the first pool = 1152
384*5 for depth of second pool = 1920
1920-1152 = 768
Answer:
1/3 (i think)
Step-by-step explanation:
Answer:
The reduced dimensions are:
Width = 12 cm
Length = 7.2 cm
Step-by-step explanation:
Original dimensions of Image:
Width = 20 cm
Length = 12 cm
Fran reduced the dimensions using a scale factor of 0.6
We need yo find dimensions of reduction.
We would multiply the original dimensions by 0.6 to find the new dimensions.
So, Width = 20 * 0.6 = 12
length = 12 * 0.6 = 7.2
So, the reduced dimensions are:
Width = 12 cm
Length = 7.2 cm
