Answer:
-20
Step-by-step explanation:
Its -20 on the number line
One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3
Solution step by step
1) Sum -4/5 to both sides
4y - 2/5y + 4/5 - 4/5 = -3 -4/5
2) Sum alike terms
18/5 y = -19/5
3) Multiply both sides by 5
18 y = -19
4) Divide both sides by 18
y = -19/18
Answer:
1st evening = 7 + 20 = 27 calls
2nd evening = 3 (20 ) = 60 call
3rd evening = 20 calls
Step-by-step explanation:
total calls for the last three evenings = 107 phone calls
2nd evening = 3x as many calls as the 3rd evening
1st evening = 7 more calls than the 3rd evening.
find:
how many calls did she receive each evening?
let T (total) = 107
let x = 3rd evening.
let 2nd = 3x
let 1st = (7 + x)
T = 1st + 2nd + 3rd
107 = (7 + x) + 3x + x
107 - 7 = 5x
100 = 5x
x = 100 / 5
x = 20
therefore,
1st evening = 7 + 20 = 27 calls
2nd evening = 3 (20 ) = 60 call
3rd evening = 20 calls
Answer:
y=3x-16
Step-by-step explanation:
-3y=-9x+27
y=3x-9
slope: 3
y-2=3(x-6)
y-2=3x-18
y=3x-16
