It would be -50 I hope this answers your question
Let x and y represent the measure of the unknown angles
x+y=145
x-y= 15
2x=160 (Use the elimination. method)
2/2x=160/2
x=80
80° is the measure of one of the unknown angles
x+y=145
80+y=145
-80 -80
y=65
The measure of the second unknown angle is 65°
Thus the measure of the unknown angles are 80° and 65°
Step-by-step explanation:
5 (18 - y) when y=6
5 (18 - 6)
5 × 18 - 5× 6
90 - 30
60
Answer:
45°
that is the answer have a nice evening
Step-by-step explanation:
f(x)=4x+7
y = 4x+7
4x = y-7
x = (y-7) /4
the correct answers are:
=> f`¹(x) = (x-7) /4 (a)
=> x - 7 = 4y (e)
=> (x-7) /4 = y (f)
=> x = 4y +7 (g)
