1. Solve for “P” A=P+Prt
2. Solve for “x” ax+3=bx-5
Please help me work out these equations
Answer:
P = A/1+rt
Step-by-step explanation:
Given: A = P + Prt
Applying the distributive principle: A = P( 1 + rt)
Dividing both sides by (1 + rt):
A/1 + rt = P

The Smiths purchased 6 containers of ice cream for a party.
Each container holds 9 cups of ice cream
Before the party, their sons ate 3 cups of ice cream altogether
What fraction of the original amount ice cream purchased did the Smiths’ sons eat?
1. 1/3
2. 2/3
3. 1/18
4. 17/18
Answer: 17/18
Step-by-step explanation: Multiply the amount of containers and the amount of cups in each container. Subtract 3. This is 51 out of 54, simplify this and get 17 out of 18.
Answer:
the answer is 1/18
Step-by-step explanation:
6×9=54-3=51.

Marjorie bought 24 bottles of juice. Each day she opens and drinks 2 of these bottles of juice. Which inequality represents the greatest number of days she can continue before she has to replenish her stock? Answers 2d>24, 2d<24, 2d≤24, 2d≥24
Answer:
2d≤24
Step-by-step explanation:
Total number of bottled juice bought = 24 bottles
Amount she drank each day = 2 bottles
To get the inequality to represent greatest number of days she can continue before she has to replenish her stock, we will say;
1 day = 2 bottles
d days = 24 bottles
Cross multiply
2 * d = 1 * 24
2d = 24
Since we want to know the greatest number of days she can continue before she has to replenish her stock, the equal to to sign will be replaced with less than or equal to sign as shown;
2d≤24
This shows that the maximum number of days she can continue before replenishing is 12days. It cannot exceed
Please Help, I don't understand how to solve this!! Will mark BRAINLIEST!!!
Explain how you solve, plz!!
Answer:
5/4
Step-by-step explanation:
First plot any2 points. Next count how many units it is High and Left/Right to get to the second point!
(Added your graph for further explaination :)
First, determine 2 points on the graph. I'd recommend to choose 2 points that are next to each other to make it easier.
Second, see how many units higher the first point you chose (on the left) is than the second point you chose (on the right). Say it is 3 units, then you mark a points 3 units above the first point.
Third, see how many units to the right the second point is to the first. If it is 5 units, you would go to the point you marked on the previous step, and move 5 units to the right. If you did it correctly, it should end up on the second point you chose. The segment you drew should kind of look like a box.
Now, make a proportion. Put how many units you rose in the second step at the top, and how many you ran at the bottom. Treat this like a fraction and simplify. You have your slope!
Going higher and to the right is the formula rise/run. How many units do you rise, how many do you go right? I recommend doing this when finding slope on a graph
Hope I helped!!!!!!!!!!!!! :)
The Garzas have a kiddie pool and an adult swimming pool in their backyard. The kiddie pool is 7 feet long. The adult swimming pool is 42 feet long. How many times as long as the kiddie pool is the adult swimming pool?
Given:
The kiddie pool is 7 feet long. The adult swimming pool is 42 feet long.
To find:
How many times as long as the kiddie pool is the adult swimming pool?
Solution:
Let adult swimming pool is x times the kiddie swimming pool.
[tex]42=x\times 7[/tex]
[tex]42=7x[/tex]
Divide both sides by 7.
[tex]\dfrac{42}{7}=\dfrac{7x}{7}[/tex]
[tex]6=x[/tex]
Therefore, adult swimming pool is 6 times the kiddie swimming pool.

y=25 and x=2
This is the only one that works.
Answer:
I got D
Step-by-step explanations
I did y2-y1/x2-x1
I did 40-25/5-2 which will equal to 15/3=5
then I did 25=2x+b
25=2(5)+b
25=10+b
subtract 10
then you will get 15
So it will be y=5x+15
if I am wrong please correct me thanks :)

What values should go in Box A and Box B to make the regrouping in the minuend correct? Vertical subtraction. First line 9.318. The digit 3 in the tenths place is crossed out and there is a box labeled A above it. The digit 1 in the hundredths place is crossed out and there is a box labeled B above it. Second line minus 4.165. Enter your answers in the boxes.
The subtraction process for the operation, 9.318 - 4.265 gives;
A = 0.2, and B = 0.11
Which process can be used for number subtraction involving decimals?The given operation is a subtraction of 4.165 from 9.318,
The numbers can be arranged as follows;

-4.165
The subtraction process is as follows:
Subtracting the numbers that have the same place values, gives;
Subtract the 0.005 from 0.008 to get 0.003 which
In the subtraction process, the 0.06 cannot be subtracted from the 0.01 on top of it.
To subtract, 0.1 is borrowed from 0.3 to give 0.3 - 0.1 = 0.2 and the borrowed 0.1 is added to 0.01 to give, 0.1 + 0.01 = 0.11
Therefore;
A = 0.2 and B = 0.11
The subtraction process is therefore;

5 8 of a rectangle is coloured red. Damien cuts this red part into a number of pieces so that each piece is 1 16 of the whole rectangle. If the area of the rectangle is 48 square centimetres, what is the area of each piece?
Answer:
3 cm²
Step-by-step explanation:
Given that:
5/8 of rectangle = red
Let area of rectangle = x
Each piece = 1/16 of whole rectangle
Area of whole rectangle = 48 cm²
Area of each piece = 1/16 of 48
1/16 * 48cm²
= 48 / 16 cm²
= 3 cm²
Hence area of each piece = 3cm²
