What is 32 percent of 25

Answers

'is' in mathematics means equal
'of' in mathematics means multiplication

32% can also be written as 32/100

$x = (32)/(100) * 25$

$x = (32)/(4)$

$\boxed{\bf{x=8}}$

32% of 25 is 8

Convert percentage into decimal: 32%/100 = 0.32
Multiply the decimal by 25: 0.32 × 25 = 8 <-- our answer.

22.88 what is the number rounded to the nearest tenth

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

System of equations are,

y = -5x + 30 .. (i)

x = 10

Now, We can find the solution as;

Plug x = 10 in equation (i);

y = - 5x + 30

y = - 5 × 10 + 30

y = - 50 + 30

y = - 20

Thus, The value of the solution to the system of equations are, (10, - 20)

The correct answer is (10,-20), because the equation already gives you the correct x value. Then, from there you just plug 10 in for x in the y equation. Giving you a -20, :)

-3x = 2x + 19 solve

Answers

Answer:

x=-19/5

Step-by-step explanation:

-3x=2x+19

-3x-2x=19

-5x=19

x=19/-5

Answer:

get x to one side by subtracting 2x from 2x+19

new equation:

-3x-2x=19

-5x=19

divide both sides by -5

x=-19/5

or x=-3 4/5

7/10 + 3/10 fined each sum and simplify

7/10 + 3/10 would equal 10/10 or 1

well add 7 by 3 which is 10 then add 10 by 10 which is 20 so 10 over 20 then divide 10 into 20 which 2 so it is 1/2

Rosa is thinking of a number between 9.04 and 9.15 that has a 6 in the hundredths place what is the number? Explain

Answers

9.06

if the 6 is in the hundreths place, with those numbers it is the only answer because the next highest would be 9.16 and that would be too high

9.06 because 9.06 is greater than 9.04 but smaller than 9.15
