Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels
1: supplementary means 180 degrees so subtract 30 from 180 and angle b is 150 degrees.
2: complementary means 90 degrees so subtract 49 from 90 and the second angle is 41 degrees.
3: a right angle is 90 degrees.
4: congruent means same size same shape so if the first angle is 40 degrees then the second angle would also be 40 degrees.
The initial fee is the base, so that will not change.
Without knowing how many miles you're going you need x to substitute them, so the equation would be (using slope intercept form)
y= 1.68x + 2.15
