Answer:
40 trees
Step-by-step explanation:
Let the total number of trees be x.
75% of all the sycamore trees in the park are 30 trees.
So,75%of x=30
or,(75/100)*x=30
or,x=(30*100)/75
or,x=40 [ANS]
12 times 11 is 132.
132 times $6 is $792
Hope this helps!
Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
The answer is 18.
Just replace the x with 2
Answer:
x=-4
Step-by-step explanation:
Subtract x from 3x ( 2x )
2x+5=-3
Subtract 5 from -3 ( -8 )
2x=-8
Divide ( -4 )
x=-4
