8 + 4 = 3x
12 = 3x
divide both sides by 3
x= 4
Answer:
Make an eqaution from here.
Let’s make evening 2 “x”
So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).
X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x
And when solved, it has to equal 105.
So solve from here.
Combine like terms.
6x-9=105
Isolate
6x=114
x= 19
First evening is 9 less then 19, so 10.
The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76
1st night = 10
2nd night= 19 calls
Thrid night= 76 calls
7a-17=4a+1
7a-4a=1+17
3a=18
a=6
ans: a=6
Answer:
18 weeks
Step-by-step explanation:
80+15x=350
15x=270
x=270/15
x=18
It tells you.
(-2, 4)
(-1, 3)
(1, 6)
(3, 5)
(4, 8)
When x is 3, y is 5. The point (3, 5) tells us that.
