Answer:
9
Step-by-step explanation:
The answer is 4 for both x and y
6 • 4 = 24
12 • 4 = 48
24 - 48 + 24 = 0
-24 + 24 = 0
-24 - (-24) = 0
To solve for x, isolate the variable x.
First get it all onto one side by subtracting 2x from both sides.
5x-2x-11=2x-2x+22
3x-11=22
Then add 11 to both sides
3x-11+11=22+11
3x=33
Then divide both sides by 3 since x is multiplied by 3 and the opposite of multiplication is division.
3x/3=33/3
x=11
Final answer: x=11
Answer:
8
Step-by-step explanation:
Let s represent the length of the shorter base and height. Then (3/2)s is the length of the longer base.
The area formula for a trapezoid is ...
A = 1/2(b1 +b2)h
Filling in the given values, we have ...
80 = (1/2)(s +3/2s)s = 5/4s²
64 = s² . . . . . . . . . . . . . . . . . . . multiply by 4/5
8 = s . . . . . . . . . . . . . . . . . . . . . take the square root
The length of the shorter side is 8.
4/9 , 2/3, 1/6, ....-2 1/2 = - 5/2
common denominator is 18
