Answer:
let x = the number of nickels
the number of pennies can be represented by (56 - x)
.05x + .01(56 - x) = 1.52
5x + (56 - x) = 152 if in the above line we multiply both sides of the equation by 100
4x + 56 = 152
4x = 96
x = 24
There are 24 nickels and 56 - 24 = 32 pennies
24 nickels are worth 24 * 5 = $1.20 and 32 pennies are obviously worth 32 cents, so the total is 1.20 + 0.32 = $1.52

Answer: 400
Step-by-step explanation: first you have to know the triangle area, which is 20 times 10 divided into 2, then you have to know the square area which is 20 times 15 and finally you will put together the areas, which is 400
V = 4/3πr³
V= 4/3π(4.8)³
V= 4/3π(110.592)
V=147.456π
Answer:
.5 × 3.2 = 1.6
This gives you 1.6, which is between 1 and 2
Step-by-step explanation:
6x+24
you have to merge together like terms .
you add 3x +3x and you get 6x
and you have to add 10+14 and you get 24
so the answer is 6x +24
