<u>Equation</u>
Let's call:
p = number of pennies Janesa has in her pocket
n = number of nickels Janesa has in her pocket
She has 24 coins in total, thus:
![p + n=24\qquad\qquad [1]](https://tex.z-dn.net/?f=p%20%2B%20n%3D24%5Cqquad%5Cqquad%20%5B1%5D)
Since each penny is worth $0.01 and each nickel is worth $0.05, and Janesa has $1 in total:

Multiplying by 100:
![p+5n=100\qquad\qquad [2]](https://tex.z-dn.net/?f=p%2B5n%3D100%5Cqquad%5Cqquad%20%5B2%5D)
A. Completing the equation:

B.
From [1]:

Substituting into [2]:

Simplifying:

Rearranging:



B. There are 5 pennies in Janesa's pocket
C. Since each penny is worth $0.01, the total value of pennies is 5*$0.01=$0.05
The total value of the pennies is $0.05
D. The total value of the nickels is 19*$0.05 = $0.95
E. Jackson should say she has 19 nickels and 5 pennies
Try C, i am not completely sure but i tried
Answer:
It is a 50% increase
Step-by-step explanation:
2.4 million /2 = 1.2 million
2.4m + 1.2m = 3.6m
50% of 2.4 is 1.2
it is a +50% increase to get from 2.4 to 3.6
Answer:
Step-by-step explanation:
note : distance between A(X1,Y1) an B (X2,Y2) is :
AB= √((X2 - X1)² + (Y2 - Y1)²)
in this exercice : X1 = -3 X2 = - 4 Y1 = 5 Y2 = 1
continue .....calculate AB
