X + (X+1)+ (x+2)=-342
3x+3 =-342
3X=-339
X=-113, -114, -115
Step-by-step explanation:
Two lines that are parallel have the same slope. If we make
in to slope-intercept form it'll be like this:

Now we know
as its slope-intercept form we can see the slope is
.
has the same slope as
so they are both parallel.
<h3>Answer:</h3>

Answer:
The number of children (n) that can attend the birthday party can be expressed as;
n≤8
Step-by-step explanation:
Step 1
We can use the expression below to calculate the total cost of the party as shown;
C≥F+(V×n)
where;
C=total cost of Gina is willing to spend
F=fixed cost for the rent
V=cost per child
n=number of children at the party
In our case;
C=$100
F=$50
V=$6.25
n=n
replacing;
100≥50+(6.25×n)
6.25 n+50≤100
6.25 n≤100-50
6.25 n≤50
n≤50/6.25
n≤8
The number of children (n) that can attend the birthday party can be expressed as;
n≤8

The answer is 10 and 10i .
