The sum of two numbers is 52. The smaller number is 18 less than the larger number. What are the numbers?

ch4aika [34]

x + y = 52

x = y - 18

Adding,

2x + y = 52 + y - 18

2x = 34

x = 17

y = x + 18 = 35

Check: x+y = 17+35 = 52, good

Answer: 17 and 35

I have a problem -3x-7=-13. When isolating x I divide x by -3 then divide -13 by -3 correct?

rosijanka [135]

Hello!

no, that is not the correct way to isolate x. you were somewhat on the right track however.

here's the correct way:

add 7 to both sides to get -3x = -6

then divide both sides by -3 to get x = 2

I hope this helps, and have a nice day!

Answer:

LP = 18

Step-by-step explanation:

Given that,

In ΔLPN,

LQ = 6, LM = 11 and MN = 22

We need to find the length of LP.

As QM ║PN, let QP = x

$\dfrac{LQ}{LP}=\dfrac{LM}{LN}\\\\\dfrac{6}{6+x}=\dfrac{11}{11+22}\\\\\dfrac{6}{6+x}=\dfrac{11}{33}\\\\198=66+11x\\\\198-66=11x\\\\132=11x\\\\x=12$

LP = 6+x

= 6+ 12

= 18

Hence, the length of LP is 18.
