Answer:
15. UA = 24
16. QW = 9
Explanation:
15. since UA = AS, we put an equal sign in between both equations
3x+3=4x−4
Step 1: Subtract 4x from both sides.
3x+3−4x=4x−4−4x
−x+3=−4
Step 2: Subtract 3 from both sides.
−x+3−3=−4−3
−x=−7
Step 3: Divide both sides by -1.
-x/-1 = -7/-1
x = 7
To find UA, we substitute x to 7
UA = 3x + 3
UA = 3(7) + 3
(3)(7)+3
=21+3
=24
UA = 24
To find AS
AS = 4x - 4
AS = 4(7) - 4
(4)(7)−4
=28−4
=24
AS = 24
16. 2x - 1 = x - 4
Step 1: Subtract x from both sides.
2x−1−x=x+4−x
x−1=4
Step 2: Add 1 to both sides.
x−1+1=4+1
x=5
Answer:
x=5
To find QW
QW = 2x - 1
QW = 2(5) - 1
2(5) - 1
= 10 - 1
= 9
QW = 9
To find WS
WS = x + 4
WS = 5 + 4
5 + 4
= 9
WS = 9
