Vinvika [58]

The value of x is √2.5

<h3>How to solve arithmetic?</h3>

Arithmetic can be solved by using PEMDAS rule.

P = parenthesis

E = exponential

M = Multiplication

D = division

A = addition

S = Subtraction

Therefore,

12 - 4 + 5x² = 20

12 - 4 +  5x² = 20

8 + 5x² = 20

5x² = 20 - 8

5x² = 12

x² = 12 / 5

x = √2.4

A car uses 8 gallons of gasoline to travel 290 miles.Juanita wants to take a trip that is 400 miles. What equation will she need
olchik [2.2K]

Answer:

To find this answer, you would need to find how many miles 1 gallon of gas will take them. To find this, you would do 290÷8=36.25. So with this information, you will be able to find out how much gas it would take to travel 400 miles. You would do 400÷36.25=11.03. 11.03 would be how many gallons of gas is used to travel 400 miles. Hope this helps! :)

A basketball player made 75% of her free throws in 10 games. She had 36 free throw tries. How many did she make?
makvit [3.9K]
If she had 36 free throw tries and made 75% of them, you would multiply 36 by 0.75.  Percentages are really just parts out of 100, so 75 in decimal form would be 0.75 (out of 1.0).

36 x 0.75 = 27   ( the same as 3/4 of 36 )

So, the basketball player made 27 free throws.
