What is the solution to the system of equations?
matrenka [14]

Hey there! I'm happy to help!

We have a 5x is one equation and a -5x in another equation. We can combine the two equations to cancel out the x and then solve! This is called solving by elimination.

5x-4y=6

+

-5x+4y=-10

0= -4

Since we lost our x and y while solving, there cannot be any solution.

Therefore, the answer is no solution.

Have a wonderful day!

Eden and Eva's mom kept track of how much each sister grew every 4 months. Eden grew 1 1/2, 7/8 and 2 inches and Eva grew 1 3/4
Katarina [22]
Answer: B (I think). Explanation: Turn the mixed fractions into improper fractions. Get a common denominator by multiplying the denominator and the numerator by the same number (common denominator is 8), then add the three improper fractions together. Eden grew 35/8 inches and Eva grew 33/8 inches. When we turn them into mixed fractions we will get, (Eden: 4 3/8) and (Eva: 4 1/8). After that, we subtract them both and get 2/8. We know that 1/4 is 2/8 since if we multiply 1/4 by 2 (by the denominator and numerator), we will get 2/8. (Sorry if you still don’t understand).

Find one solution for the equation. Assume that all angles involved are acute angles.
Nikitich [7]

9514 1404 393

Answer:

  B = 13

Step-by-step explanation:

The tangent and cotangent are equal when the angles are complementary.

  (3B +35) +(2B -10) = 90

  5B = 65

  B = 13

___

<em>Check</em>

For B=13, the angles are 3B+35 = 39+35 = 74, and 2B-10 = 26-10 = 16. Both are acute angles.
