120=100%

x= 7 %

cross-multiply

100x= 120*7

100x= 840

x= 840/100

x= 42/5

x= 8.4

Therefore 7% of 120 is 8.4


I hope that's help !

1% of 120 is 1.2, so 7 *1.2 = 8.4

Also you could set up the proportion 7/100 = x/120 and solve for x.

Answer:

  1. 15 - 7 (Parentheses)
  2. 3² (Exponents)
  3. 8 × 2 (Multiplication)
  4. 40 ÷ 8 (Division)
  5. 5 + 9 (Addition starting from the leftmost)
  6. 14 + 16 (Addition after the first addition operation)

Concept:

When encountering questions that ask for simplifying expressions through operation, following the PEMDAS method would be easier:

  • <u>P</u>arentheses
  • <u>E</u>xponents
  • <u>M</u>ultiplication
  • <u>D</u>ivision
  • <u>A</u>ddition
  • <u>S</u>ubtraction

Therefore, the whole process of simplifying the given expression should follow the PEMDAS method. <u>For extra</u>, whenever there are two occurences of the same operation, then prioritize the leftmost and go right.

Hope this helps!! :)

Please let me know if you have any questions or need further explanation

Shelby made $200 from selling candy bars. Large, x, candy bars sell for $4 each and smaller, y, candy bars sell for $2 each. Wri
babymother [125]

Answer:

The Equation is

4x+2y= 200

Then total number of candy bars is

X+Y

Step-by-step explanation:

Shelby made $200 from selling x at $4 each and y at $2 each.

Let's have in mind that x is the number of large candy bars

And y is the number of small candy bars

The equation is simple

The amount it was sold is going to be the coefficient of the numbers we don't Know...

So

Equation is

4x+2y= 200

Then total number of candy bars is

X+Y

Answer:

3 1/4

Step-by-step explanation:

1) Convert 6 1/2 into a fraction and add it to 1/2.

6 -> 12/2

12/2 + 1/2 = 13/2

2) Divide the result by 2 (or multiple the result by the reciprocal of 2)

13/2 x 1/2 = 13/4 or 3 1/4

Hope this helped ^^

List the steps to solve the following equation: 5x - 6 = 44 then solve x
Dafna1 [17]

Answer:

1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.

2. Divide 5 from both sides and get x = 10
