Step 1: Simplify both sides of the equation.
p−7=3
Step 2: Add 7 to both sides.
p−7+7=3+7
p=10
Answer:
The answer to your question is below
Step-by-step explanation:
The slope is the coefficient of the x, and the y- intercept is the number after the x.
Slope y-intercept
1. y = 3x - 1 3 -1
2. y = -2/5x + 4 -2/5 4
3. 7 = .5x 0.5 0
a) Order the slopes from least to greatest
-2/5, 0.5, 3
b) Order y-intercept from least to greatest
-1, 0, 4
Answer:
11 pennies and 9 nickels
Step-by-step explanation:
Set up a system of equations where p is the number of pennies and n is the number of nickels:
p + n = 20
0.01p + 0.05n = 0.56
Solve by substitution by rearranging the first equation:
p + n = 20
p = 20 - n
Then, plug this in as p into the second equation, and solve for n:
0.01p + 0.05n = 0.56
0.01(20 - n) + 0.05n = 0.56
0.2 - 0.01n + 0.05n = 0.56
0.2 + 0.04n = 0.56
0.04n = 0.36
n = 9
Then, plug this into the first equation to solve for p:
p + n = 20
p + 9 = 20
p = 11
So, Jayden has 11 pennies and 9 nickels
