50%
24 *x/100 = 12...so then 24x/100 = 12.
then x= 12 *100/24
so x =50%/
**but if u are not sure at these problems first see. that $24 she percent of it is 12 which is exactly half. So 50% off makes sense. 50%
ALSO...in math of can mean multiply..that can help u remember
A squared +b squared =c squared
so 24x24=576
18x18=324
576+324=900
square root of 900=30
the diagonol is 30
Answer:
Well reorder y and - x So the Answer to the question
- x + y Hope this helps :)
Step-by-step explanation:
Well what ever you do to one side, you do to the other.
Your goal is to get the x alone
in order to do that we divide both sides by 4
4x = 16
÷4 = ÷4 The left side cancels out and the right side gets solved
********* because 16 ÷ 4 = 4 :)
x = 4
And there's your answer
x = 4
When in doubt, eat a pineapple :)
Answer:
C 14n - 8
Step-by-step explanation:
area of rectangle = length × width = 12n² - 19n - 21
width = 3n - 7
so, what do we need to multiply with width to get the expression of the area ?
4n + 3
(because we think, what do we need to multiply 3n with to get 12n², and what to multiply -7 to get -21)
control : (3n-7)×(4n+3) = 12n²-28n+9n-21 = 12n²-19n-21
perimeter is now 2× length + 2× width
p = 2(3n-7) + 2(4n+3) = 6n - 14 + 8n + 6 = 14n - 8
