If UT is a midsegment of QRS, find SQ A. 8 B. 10 C. 16 D. 20

sladkih [1.3K]

If UT is the midsegment of QRS, then SQ = 2(2x + 2) = 4x + 4
Then,
(3x + 1)/(7x - 1) = (2x + 2)/(4x + 4) = 1/2
2(3x + 1) = 7x - 1
6x + 2 = 7x - 1
7x - 6x = 2 + 1
x = 3

Therefore, SQ = 4(3) + 4 = 12 + 4 = 16.

What is -3(4x+3)+4(6x+1)? What is X when the answer is 41?

AlexFokin [52]

First distribute the -3 to 4x + 3
It'll be -12x - 9

Then distribute 4 to 6x+1
It'll be 24x+4

-12x - 9 + 24x + 4 = 41
Add the like terms
12 x -5 = 41
12 x = 46
x = 46/ 12

In fractions the answer is 23/6
In decimals the answer is 3.84

Make x the subject of the following: b = x - 5

ipn [44]

When it says "the subject", it only means you need to isolate the x, or solve for x. To do that, we have to get the x by itself. But how can we do that? We'll have to get rid of that pesky -5. Well, what can we do to -5 to get to 0? Of course -- Add 5!
b=x-5
+5

But whatever we do to one side of the equation, we have to do to the other.
b=x-5
+5 +5

We're left with b+5=x. There's your answer!
