Answer:
x = 10
Step-by-step explanation:
Use CPCTC (Corresponding parts of congruent triangles are congruent).
Set the ratios:
First, simplify. Combine like terms:
Next, cross multiply.
Isolate the variable, x. Divide 6.5 from both sides of the equation:
Check:
Plug in 10 for x (Your answer). Cross multiply, then simplify:
(True).

100 – 2x < 20
−2x + 100 < 20
−2x + 100 − 100 < 20 − 100
−2x < −80
−2x/2 < −80/2
x > 40
Answer:
The first three options are the correct answers
Step-by-step-explanation:
1 × 24 = 24
2 × 12 = 24
3 × 8 = 24
Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.
