Answer:
<u>n=-6</u>
Step-by-step explanation:
First, distribute the 5 and the -
5n+20-n-7=-11 now combine like terms,
4n+13=-11 subtract 13 from each side
4n=-24 divide by 4
/4 /4
<u>n=-6</u>
90 hours. If you divide the total number of gallons (6750) by the rate of 75 gal/hour, it will take 90 hours to fill the whole pool.
Answer:
see the graph below
Step-by-step explanation:
If you add 1-y to both sides, the equation will be in intercept form:
x/3 - y = 1
This tells you the x-intercept is (3, 0) and the y-intercept is (0, -1).
The graph of the equation is the line through these points.
_____
<em>Comment on intercept form</em>
When the equation is written as
x/a + y/b = 1
the x-intercept is "a", and the y-intercept is "b".
I find it convenient to use this form when I want to find both intercepts of the linear equation.
12-20.5=
-8.5
The answer is C.
She has 21 eggs total; 7*3 is 21 and it can't be grouped by those numbers.
