3 0

Answer:

The variable is the number of clothes sold 'x'.

The equation is: 118.50=100+0.25x

The number of clothes sold by Lynn are 74.

Step-by-step explanation:

Let the number of pieces of clothes sold be 'x'.

Given:

Earning of Lynn per cloth is $0.25.

Fixed earning of Lynn per day is $100

Total earning after selling 'x' clothes is $118.50.

Variable: Number of clothes 'x'.

Equation:

Earning of Lynn for 1 cloth = $0.25

∴ Earning of Lynn for 'x' clothes = 0.25\times x=0.25x

Now, total earning of Lynn is the sum of fixed earning and earning from selling 'x' clothes. Therefore,

Total earning = Fixed earning + Earning for 'x' clothes

⇒118.50=100+0.25x

Solution:

Add -100 both sides and then divide the result by 0.25 both sides. This gives,

118.50-100=100-100+0.25x\\0.25x=18.50\\x=\frac{18.50}{0.25}=74

Therefore, the number of clothes sold by Lynn are 74.

If x = 3 and Y = 5 work out the value of 2x squared + 3 Y squared
miskamm [114]

Answer:

Step-by-step explanation:

x = 3

y = 5

2x^2 + 3y^2 = 2 × 3^2 + 3 × 5^2

= 2 × 9 + 3 × 25

= 18 + 75

= 93

A scientist removed a sample of 39.1 grams of a chemical from a container. The sample was 5 3/4 grams less than 3/10 of the tota
Oksanka [162]

The first thing we must do for this case is to define variables:

x: the total mass of the chemical in the container

y: a sample of a chemical from a container

We have the following equation:

y = (3/10) x - 5 3/4

Then, for y = 39.1 we have:

39.1 = (3/10) x - 5 3/4

Clearing x:

(3/10) x = 39.1 + 5 3/4

(3/10) x = 44.85

x = (10/3) * (44.85)

x = 149.5 grams

Answer:

the total mass in grams of the chemical in the container before the scientist removed the sample of 39.1 grams was:

x = 149.5 grams.

given the equation y = 2x - 8, find the ordered-pair solution when x = 4 and the ordered-pair solution when y = 4
babunello [35]

Answer:

When x = 4, (4, 0)

When y = 4, (6, 4)

Step-by-step explanation:

To find the ordered-pair solution when x = 4, plug 4 into the x of the equation.

y = 2x - 8

y = 2(4) - 8

y = 8 - 8

y = 0

This produces the ordered pair (4, 0).

To find the ordered-pair solution when y = 4, plug 4 into the y of the equation.

y = 2x - 8

4 = 2x - 8

12 = 2x

6 = x

x = 6

This produces the ordered pair (6, 4).
