4.5 is 75% of what number

Mathematics
1 answer:
il63 [147K]3 years ago
6 0

Answer:

The answer is 6

Step-by-step explanation:

4.5 = 75% × Y

4.5 =  

75

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 75 we will arrive at:

Y = 4.5 ×  

100

75

Y = 4.5 × 100 ÷ 75

Y = 6

7n2 + 5 = 453<br> Solve the quadratic function
Reptile [31]

7n^2 + 5 = 453

Subtract 5 from both sides:

7n^2 = 448

Divide both sides by 7:

N^2 = 64

Take the square root of both sides:

N = 8

-616

Step-by-step explanation:

None of these answers are correct... maybe you entered the equation in wrong. There are no variables so answers B,C, and D would be incorrect. And A is incorrect as well. Again, check the equation... may be wrong.

How do you find "a" in -10+a=6a-7a please help I do not know how to find what the answer is.
Sunny_sXe [5.5K]
-10 + a = 6a - 7a

Rearrange the left hand side

a - 10 = 6a - 7a

Simplify 6a - 7a

a - 10 = -a

Add a on both sides

2a - 10 = 0

Add 10 on both sides

2a = 10

Divide by 2 on both sides

a = 5
