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!

Step-by-step explanation:
143/13=11
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).
Answer:
$0.78
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 2.6 × 70/100
Discount = 2.6 x 0.7
You save = $1.82
Final Price = Original Price - Discount
Final Price = 2.6 - 1.82
Final Price = $0.78

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.
