Answer:
-2
Step-by-step explanation:
y=k/x
Replace y with 7 and x with -2
7=k/-2 gives you -14
Then you can replace k with -14 and x with 7
y=-14/7 gives you -2
25a + 5b - 13
5(5a + b) - 13 is your answer
using the distributive property, we can distribute 5 to all terms within the parenthesis:
5(5a + b) - 13 = 25a + 5b - 13
5(5a) = 25a
5(b) = 5b
25a + 5b - 13 = 25a + 5b - 13 (True)
hope this helps
Answer:
x = 32, y = 51
Step-by-step explanation:
You know the longest side of ΔTUS is 13m and the longest side of ΔMNP is (2x-y). Thus:
2x - y = 13 --- Equation 1
You know the sum of angles in a triangle is 360°. Two of the angles are given in ΔMNP (142° & 24°) and the remaining angle is (2x-50)°. Thus:
142 + 24 + 2x - 50 = 180
2x + 116 = 180
2x = 180 - 116
2x = 64
x = 64 ÷ 2
x = 32 --- Equation 2
Substitute x = 32 into Equation 1:
2(32) - y = 13
64 - y = 13
-y = 13 - 64
= -51
y = 51 --- Equation 3
