The nearest whole number is 20.
Answer:
Step-by-step explanation:
We first have to write an expression for each of the types of coins in terms of one of them. If he has 8 more dimes than nickels, let's call nickels "x". That means that dimes is "x + 8". The value of a nickel is .05, so the expression relating the number of nickels to the worth of the nickel is .05x. The value of a dime is .10, so the expression relating the number of dimes to the worth of the dime is .10(x + 8). The total value of these coins is 1.70:
.05x + .10(x + 8) = 1.70 and
.05x + .10x + .8 = 1.70 and
.15x = .9 so
x = 6
That means we have 6 nickels and 14 dimes.
Answer:
y = 5/7x + 5
Step-by-step explanation:
If you replace the x and y in the equation with points x and y of point (35, 30) and change the 10 to b you can solve for b which is the what changes from the original equation to this one.
30 = 5/7(35) + b
30 = 25 + b
5 = b
Since the equations are parallel they have the same slope.
This is the equation for a parallel line that passes through point (35, 30):
y = 5/7x + 5

9x - 37 = - 118
add 37 to both sides
9x - 37 + 37 = -118 + 37
simplify
9x = -81
divide both sides by 9
9x/9 = -81/9
simplify
x = - 9
answer
x = -9
