Answer:
x = 9
Step-by-step explanation:
for any two intersecting chords, the product of their section lengths will be identical.
20(2x + 3) = 14(3x + 3)
40x + 60 = 42x = 42
18 = 2x
x = 9
The answer is -6 < x < 9.
can u mark me as brainliest?
<span> 3( x + 1 ) = - 2 ( x - 1 ) + 6 </span>
<span>1) Clear the parentheses by distributing the 3 and the - 2 </span>
<span>When you have done that, this is what you will get: </span>
<span>3x + 3 = - 2x + 2 + 6 </span>
<span>2) Combine the like terms on the right </span>
<span>You will get this: </span>
<span>3x + 3 = - 2x + 8 </span>
<span>3) Add 2x to both sides to collect all the x terms together on the same side </span>
<span>When you finish doing that, you will have </span>
<span>5x + 3 = 8 </span>
<span>4) Subtract 3 from both sides to isolate the 5x term alone on one side </span>
<span>You will get </span>
<span>5x = 5 </span>
<span>5) Divide both sides by 5 to isolate x </span>
<span>x = 1 <-- answer</span>
Answer:
80%
Step-by-step explanation:
4500 × y = 100 × 3600
4500y = 360000
4500y ÷ 4500 = 360000 ÷ 4500
y = 80
