Answer:
x = -5
Step-by-step explanation:
2x = -10 <== divide both sides by 2
/2 /2
x = -5
Check your work:
2x = -10
2(-5) = -10
-10 = -10
This statement is true
Hope this helps!
Answer:
0.003, 5/1000, 9/1000
Step-by-step explanation:
0.003 is thousandths.
5/1000 is thousandths.
9/1000 is thousandths.
I converted them to fractions.
5/1000 is already a fraction
Same for 9/1000
0.003=3/1000
So 3/1000, 5/1000, 9/1000
Answer:
300
Step-by-step explanation:
the nth term of a sequence is 3n^2 (where n only is squared), then the 10th term of the sequence is; 3 x (10)^2= 3 x 100 = 300.
The trick to solving this problem is to realize that the independent variable is x, which represents the number of people who can attend the party without the total party cost exceeding $80.
This is the form of the inequality:
(total cost) [less than or equal to] $80
(rent) + (cost per guest)(number of guests) [less than or equal to] $80
$45 + $5.50 x [less than or equal to] $80
Simplify. To do this, subtract $45 from both sides of this inequality.
Divide both sides of the resulting inequality by $5.50.
What is the restriction on x?
For
ax+by=c
the slope is -a/b
the slope of paralell lines are the same
fidn slope
5x+3y=15
-a/b=-5/3
paralell as same slope
answer is A
