4 feet tall
Step-by-step explanation:
You can solve this equation by taking 2.5/5 to get 0.5, and then by taking 0.5 times 8 to get 4.
Answer:
50
Step-by-step explanation:
let the number be x
15% of x= 0.15x
0.15x=30
(divide both sides by 0.15)
x= 200
25% of 200 = 25/100 *200
= 50
Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
Answer:
The value is 13
Step-by-step explanation:
Means absolute value. This means no matter the sign of the number (negative or positive) we are just looking for the value of the number

Answer:
Answers A and B
Step-by-step explanation:
To divide fractions, you keep, change, flip. Keep the first fraction the same, 4/11. Change the division sign into a multiplication sign. Finally, find the reciprocal or "flip" the last fraction into 15/9. This makes the equation 4/11 x 15/9. Multiply across the top to get 60, and the bottom to get 99. This makes 60/99. Therefore, answer A is correct. Find some more equivelent fractions by multiplying or dividing the top and bottom by the same amount. In this proccess, you can find that answer B is also correct.
