1 answer:
kakasveta [241]3 years ago

Answer:

C (let me know if I am wrong!)

Step-by-step explanation:

We need to solve the equation.

If 5x+y = -24, then -24 - 5x = y.

x+ 3(-24-5x) = -2

= -14x-72=-2

= -14x-72+72=-2+72

= -14x=70

= -5

If x = -5, then -5 + 3y = -2.

3y = -2+5

3y = 3

y=1

So the answer is C.

6. Find JL.<br> Please and thank you. 5x-16=3x+4
IRINA_888 [86]

Answer:

JL = 68

Step-by-step explanation:

JM = ML

Hence, 3x + 4 = 5x - 16

Subtract 3x from both sides

4 = 2x - 16

Add 16 to both sides

20 = 2x

Divide both sides by 2

10 = x

Now we want to find JL

Note that JL = JM + ML

JM = 3x + 4 and x = 10

Substitute 10 for x

3(10) + 4

Multiply

30 + 4

Add

JM = 34

Because JM = ML

We simply multiply 34 times 2 to find the length of JL

34 * 2 = 68

JL = 68
