Answer:
im pretty sure it would be a.
Step-by-step explanation:
55x3 = 165, and 12x would mean the money times the amount of used he bought. so therefore it is a.
<span>If 3 is added to the number: x + 3
b) ...and the sum is tripled..
"The sum" is "x + 3" so: 3(x+3)
c) ...the result is 27 more than the number.
27 more than the number is x + 27
d) Put it all together:
3(x + 3) = x + 27
Solve for x:
1) Distribute the left side of the equation:
3x + 9 = x + 27
2) Subtract x from each side of the equation:
2x + 9 = 27
3) Subtract 9 from each side of the equation:
2x = 18
4) Solve for x:
x = 9
Check:
1) x = 9
2) 3(x + 3) = x + 27
3) 3 ([9] + 3) = [9] + 27
4) 3(12) = 9 + 27
5) 36 = 36
So, therefore The answer is correct</span>
Geogra will have a 64% he got 9% wrong
let the no. be x
41/50 - x = 18/25
x=41/50 - 18/25 = (41 - 36)/50 = 5/50 = 1/10
1/10 should be subtracted from 41/50 to get 18/25
HOPE THIS WILL HELP U
You have to put -2 in as x for the equation.
f(-2) = 5(-2) +3
f(-2) = -10 +3
f(-2) = -7
