Solve:
10c + 20 = 40
c =

Answers

Answer 1
C= 2


...................................
Answer 2
The correct answer is 2.

Step 1: in order to solve an equation, you need to isolate the variable. Meaning, you need to get it by itself In this case, the variable is c. So, what you will do is subtract 20 on both sides of the equation and you should end up with 10c=20.

Step 2: We still need to get c by itself so, we have to do the inverse operation of multiplication, which is division. We then divide 10 on both sides of the equation. The answer you should come up with is c=20

Hope this helps! Have a great day/night:)

The sale price of an item is $160 after a 20% discount. What was the original price of the item?

Answers

Answer:

200 sorry read that wrong

Step-by-step explanation:

Answer:

The original price of the item is $200.

Step-by-step explanation:

Let the original price be 'x'.

The sale price of an item is $160 after a 20% discount.

i.e. original price - 20% of original price = $160

x-20/100x=160

x-0.2x=160

0.8x=160

x=160/0.8

x=200

Therefore, the original price of the item is $200.

2 2/7 :(0.6x)= 4/21 :0.25 help pls BTW ITS NOT 50 !!

answer: x=0.025253

Step-by-step explanation:

Let's solve your equation step-by-step.

22

7

(0.6x)=

4

21

(0.25)

Step 1: Simplify both sides of the equation.

1.885714x=

1

21

Step 2: Divide both sides by 1.885714.

1.885714x

1.885714

=

1

21

1.885714

x=0.025253

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25

Therefore, solve the mixed fraction, we get

16/7 :(0.6x) = 4/21 :0.25

Step 1: Simplify both sides of the equation.

16/7 :(0.6x) = 4/21 :0.25

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Step 2: Divide both sides

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Cross multiply:

(16/7) x (0.25 )= (4/21 ) x (0.6x)

4/7 = 2.4x /21

84 = 16.8x

Divide both sides by 16.8:

x = 5

The first side of a triangle is 7 cm shorter than twice the second side. The third side is 4 cm longer than the first side. The perimeter is 90 cm. Find the length of all three sides.

Please answer! Im giving half of all my points!!

Answers

Answer:

first side = 33

second side = 20

third side = 37

Step-by-step explanation:

first side = 2x-7

second side = x

third side = (2x-7)+4

(2x - 7) + x + (2x - 7) + 4 = 90

5x - 14 + 4 = 90

5x - 10 = 90

     +10  +10

5x = 100

x = 20

first side:

2(20)-7

40 - 7 = 33

second side: 20

third side:

(2(20) - 7) + 4

(40 - 7) + 4

33 + 4 = 37

3c + 1 = 10 Need help with this I have so many assignments to do Help me Please and Thank you!

Answers

Answer:

c = 3

Step-by-step explanation:

You are solving for the variable, c. Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 1 from both sides of the equation:

3c + 1 = 10

3c + 1 (-1) = 10 (-1)

3c = 10 - 1

3c = 9

Next, divide 3 from both sides of the equation:

(3c)/3 = (9)/3

c = 9/3

c = 3

c = 3 is your answer.

~

c = 3 because 3 x 3 is 9 + 1 is 10
