If it costs $16.50 to bowl twice with a shoe rental and $28.50 to bowl 4 times with a shoe rental how much does the shoes cost
Dmitry_Shevchenko [17]

Answer:

Shoe rent is $4.5

Step-by-step explanation:

Let the shoe rent is "x" which will remain the same irrespective of the number of bowling and "y" is bowling.

thus, x + 2y = 16.50

Rewrite, x = 16.50 - 2y

When bowling is 4 time then:

x + 4y = 28.50

Rewrite, x = 28.50 - 4y

Now solve both equations for the value of "y".

Thus, 16.50 - 2y = 28.50-4y

-2y + 4y = 28.50 - 16.50

2y = 12

y = 6

Insert y = 6 in the x - 2y = 16.50

x = 16.50 - 2y

x = 16.50 - 2 (6)

x = $4.5

Shoe rent is $4.5

What is the answer for finding the slope from two points. Please help I am very confused
Nataly [62]
Slope = \frac{y2 - y1}{x2 - x1}
------------------
Substitute as followed
y2 = 4
y1 = 1/2
x2 = 1/2
x1 = 2
Slope = \frac{4- \frac{1}{2} }{ \frac{1}{2}-2}
--------------------------
Solve
4 - 1/2 = 7/2
1/2 - 2 = -3/2
\frac{7/2}{-3/2}
-7/3 = slope

A 1.51 gram bar of gold is worth 1567.01 dollars. what is the value in dollar of a 2.23 gram of gold ingot?
marin [14]

Answer:

Step-by-step explanation:

1.51 gram to $ 1567.01 = 2.23 gram to $ x

1.51 / 1567.01 = 2.23 / x

cross multiply because this is a proportion

(1.51)(x) = (1567.01)(2.23)

1.51x = 3494.43

x = 3494.43 / 1.51

x = $ 2314.19 <===== what 2.23 grams of gold is worth

==========================

x = first car and y = new car

x = 28,033.51

y = 2x - 301.26

y = 2(28,033.51) - 301.26

y = 56,067.02 - 301.26

y = $ 55,765.76 <====== new car cost

Use substitution to solve the system of equations.
gtnhenbr [62]
(3.75, 5.5)

(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.
