Enter the value of x that makes the equation 5+3x-37=6x+23-8x

Answers

Answer:

x=-7

Step-by-step explanation:

Answer:

x=11

Step-by-step explanation:

5+3x-37=6x+23-8x

add like terms

-32+3x=-2x+23

add 2x to both sides

-32+3x+2x=23

add 32 to both sides

3x+2x=23+32

add like terms

5x=55

divide by 5 on both sides

x=11

A rectangular chocolate bar is made of equal squares. Irena breaks off two complete strips of squares and eats the 12 squares she obtains. Later, Jack breaks off one complete strip of squares from the same bar and eats the 9 squares he obtains. How many squares of chocolate are left in the bar?

Answers

Answer:

There are three more square chocolates left

Step-by-step explanation:

We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)

The number of Squares of chocolate left in the bar is; 15 squares

What is the amount of squares left?

A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.

It means that each of the vertical height must also contain 6 squares as well.

Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.

Now, Jack ate 9 squares and so;

Amount of squares left = 25 - 9 = 15

Explain how to solve the equation

b-7=12

Answers

Answer:

[tex]b = 19[/tex]

Step-by-step explanation:

1) Add 7 to both sides.

[tex]b = 12 + 7[/tex]

2) Simplify 12 + 7 to 19.

[tex]b = 19[/tex]

Therefor the answer is, b = 19.

Answer:

Sample Response

Step-by-step explanation:

Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.

Jasmine invests 2658 in a retirement account with a fixed annual interest rate of 9% compounded annually what will the account balance be after 4 years

Answers

Without making a function out of it, all you need to do is the initial amount 2658$ x 1.09 (1,09 is like adding 0,09 to the total amount 1,00. Which, in % is adding 9% to the total amount 100%.)
= 2897.22$

Since it is compounded every year, you redo the same operation but on the new higher sum you just got.
