HELP ASAP will give BRAINLIEST
tester [92]

Hey there! I'm happy to help!

The question tells us that m∠JKL is 54. We see from the diagram that this is the combination of the angles m∠JKM and m∠MKL. So, we can combine their values, which are equal to 54 to find x.

13x+1+5x+4=54

We combine like terms

18x+5=54

We subtract 5 from both sides.

18x=49

We divide both sides by 18.

x=2.7222222....

Now, we want to find the measure of m∠MKL. We plug our x value into the value of this angle and evaluate.

5(2.722....)+4=17.61111....... or 17 11/18.

Have a wonderful day and keep on learning! :D

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must
Nuetrik [128]

Let w be the amount of water that evaporates. At the start, the solution in the tub consists of 2.5 gallons of salt (5% of 50 gallons). After w gallons of water evaporates, we're left with a solution with total volume 50-w gallons, and 8% of this amount should be salt, or 0.08(50-w) gallons of salt. The amount of salt in the tank before and after evaporation remains unchanged, so

2.5=0.08(50-w)\implies2.5=4-0.08w\implies0.08w=1.5\implies\boxed{w=18.75}

gallons of water need to be evaporated.

Answer:

Dr. Nemur appears to be uncomfortable around me. Sometimes when I try to talk to him, he just looks at me strangely and turns away. I was angry at first when Dr. Strauss told me I was giving Dr. Nemur an inferiority complex. I thought he was mocking me and I’m oversensitive at being made fun of.

What is the value of y?
dimaraw [331]
All angles in a triangle = 180. SO we can make an equation to find y:
79+37+y=180
116+y=180 (combine like terms)
y=64 (subtract the 116)
