3 - 2x + 5 < -4(x + 2)
-2x + 8 < -4(x + 2)
-2x + 8 < -4x - 8
-2x + 8 + 4x < -8
2x + 8 < -8
2x < -8 - 8
2x < -16
x < -16/2
x < -8
Answer: A) x < -8
4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
Answer:the sector is 280°
Step-by-step explanation:
11 i think is what the answer is.
if x is the bigger num and y is the smaller
x + y = 91
x - 3y = 7.7
multiply by -1
x+y = 91
-x + 3y = -7.7
add the equations
4y = 91 - 7.7
4y = 83.3
y = 20.825
then x+y = 91 use to find x
x+20.825 = 91
x = 70.175
the two numbers are 70.175 and 20.825
