Jacqueline has two part-time jobs. She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier. This is modeled by 15l+12s. Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week.

Answers

To find the total amount of money Jacqueline will earn this week, we need to substitute the values l=5 and s=7 into the expression 15l+12s and evaluate the result. This gives us 15*5+12*7=75+84=159. Therefore, Jacqueline will earn a total of $159 this week from her two part-time jobs.

Jacqueline will earn $159 at her two jobs this week.

What is an expression?

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given;

Jacqueline has two part-time jobs.

She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier.

This is modeled by 15l+12s.

We have the expression,

15l + 12s

To find the value of the expression:

Substitute the value of l and s to the expression.

We have l = 5 and s = 7.

So,

15(5) + 12(7)

= 75 + 84

= 159

Therefore, she will earn $159.

A slope of 1 is a positive slope, so the line has to go up to the right.

A value of 6 for b means the y-intercept is 6.

Jabari had two equations to solve. Both had two unknowns, x and y. Jabari could use them to solve each other. That's called (_______). Jabari decided to (_______) using the substitution method. First, he had to turn the x's in one equation into y's. He subtracted 2y from both sides of the first equation x+2y = 4. This made x = 4−2y.
Next, he substituted the expression 4−2y for x in (_______). Now he had (4-2y)−2y = 6.
Jabari saw that the two 2y's were like terms. He knew that collecting like terms is a way to (_______). He combined the y's to get 4−4y = 6.
From there, he subtracted 4 from both sides to get −4y=2. Now it was easy to evaluate the expression down to a single value. The problem's solution was (_______).

Leandro has four cubes like this one: He sticks them together to form the solid shown here and paints it blue all over. A week later, he separates the four cubes. What fraction of the total number of faces is WHITE?

Answers

Answer:

Step-by-step explanation: Each cube has a total of 6 sides. In the model, the top cube has 1 "hidden" side/1 side that is not exposed to the paint, the bottom middle has 1 "hidden" side, the right bottom cube has 1 "hidden" side, and so does the left. Adding up all the sides that are not exposed to the paint, there is a total of 4 white sides.

6 x 4 = 24 meaning there is a total of 24 faces

The cubes are stuck together in three places

2 faces are glued at once

2 faces x three places = 6

6/24 faces are white

K-Mart is open Monday through Saturday from 8:00 AM to midnight and Sunday from 10:00 AM to 8:00 PM. How many hours is it open in one week

Answers

Answer:

Step-by-step explanation:

K-Mart is open Monday through Saturday from 8:00 AM to midnight and Sunday from 10:00 AM to 8:00 PM. How many hours is it open in one week?

24:00 - 8:00 = 16:00 (16 hours) per day Monday to Saturday

16:00 * 6 = 96:00 (96 hours) total Monday to Saturday

20:00 - 10:00 = 10:00 (10 hours) Sunday

96:00 + 10:00 = 106:00 (106 hours) total

Here, we know that on each month 1 cm every month so it's increased 24 cm after 24 months

Therefore

H = 52 + m

H = 52 + 24

H = 76 cm

Thus, The height of the plant is 76 cm after 24 months.
