Ashley has some pennies and some nickels. she has at most 22 coins worth a minimum of $0.78 combined. if ashley has 4 pennies, determine the minimum number of nickels that she could have. if there are no possible solutions, submit an empty answer.

The minimum number of nickels that she could have is 15

Step-by-step explanation:

Let x represent the number of nickels Ashley has. If she has 4 pennies and has at most 22 coins, then

→ x + 4 <= 22

→ x <= 18    (1)

Her coins worth a minimum $0.78. Also, it is known that 1 dollar is equal to 100 cents and 1 nickel is equal to 5 cents.

→ (x * 5) + 4 >= 78

→ 5x >= 74

→ x >= 14.8  (2)

If we combine the equation 1 and 2:

14.8 <= x <= 18

The minimum value of x is 15

536

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
