Answer:
{}
Step-by-step explanation:
y=5-2x ............. simplication
2x+5-2x=15
5=15 so it have no real solution
2.75
Sorry about the blurry photo and hope this helps
Answer:I think it’s 269 because when you do 1,350 divided by 50 it’s 27 then you add 9+2 to get 11/50 then you do 27x11 which gives you 270 and the closest answer to that is 269
Step-by-step explanation:
Answer:
(3, 3)
Step-by-step explanation:
Apparently, you want to find the value of y that corresponds to the value x=3. Put x=3 into the equation and do the arithmetic.
y = 4(3) -9 = 3
The missing value is 3, and the ordered pair is ...
(3, 3)
Answer:
x=40
Step-by-step explanation:
80°+(2x+20)°= 180°... (co-interior angles are supplementary)
2x=180 - 80 - 20
2x=80
(divide both sides by the coefficient of x which is 2)
x=80÷2
x=40
Check:
(2x+20) must be equal to 100
Let x=40
Therefore :
2X40+20
=100
