Step-by-step explanation:

Cashier: 8$/ hr

Tutor: 12$/hr

made $268 for 30 hours

C = # of hours for cashier

T= # of hours for tutor

*For these type of equations, keep $ with $ and quantity with quantity

So you would the 8/hr to 12/hr to equal the total money and add the quantity(in this equation c and t) with the total hours.

Decrease 112kg by 3/8

Answers

Answer:

70 kg

Step-by-step explanation:

[tex]\frac{5}{8}*\frac{112}{1}kg\\\frac{5}{1}*\frac{14}{1}kg\\5 * 14kg\\70 kg[/tex]

Decreasing 112kg by 3/8 is equal to 70kg.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

3/6, 99/999 is a fraction.

1/4 is a fraction.

We have,

To decrease 112kg by 3/8,

we can multiply 112 by 3/8 and then subtract the result from 112:

112 - (112 x 3/8)

First, we simplify 3/8 by finding a common denominator of 8:

= 3/8

= 3/8 x 8/8

= 24/64

So we have:

112 - (112 x 24/64)

To simplify this expression, we can first divide both the numerator and denominator of 24/64 by the greatest common factor, which is 8:

= 24/64

= (24 ÷ 8) / (64 ÷ 8)

= 3/8

Substituting this value, we get:

112 - (112 x 3/8)

Multiplying 112 by 3/8, we get:

= (112 x 3/8)

= (336/8)

= 42

Substituting this value, we get:

= 112 - 42

= 70

Therefore,

Decreasing 112kg by 3/8 is equal to 70kg.

If the ball started its flight at a height of 8 feet, then its height s at time t can be determined by s(t)=-16t^2+48t+8 where s(t) is measured in feet above the ground and t is the number of seconds of flight.

y = 88

Step-by-step explanation:

66 + 26 + x = 180 (collect like terms)

92 + x = 180 (subtract 92 on both sides)

x = 88

y = x

y = 88

Answers

Answer:

Step-by-step explanation:

The equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope is -1/2

Using point-slope form, the equation of the line can be written as:

y - y₁ = m(x - x₁)

Substituting the values given in the problem, we get:

y - 1 = (-1/2)(x - (-6))

y-1=-1/2(x+6)

y-1 = -1/2x -3

y=-1/2x-2

Hence, the equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.
