Let the number of hamburgers = h
Let the number of cheeseburgers = c
Now we translate the given information into equations.
"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770
<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70
The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350
Answer: 350 hamburgers were sold on Monday.
I will be glad to help you in the comments. I do need to know though, what is the class this is presented in? Is this algebra, or calculus? Depending on the class, we have different approaches.
Answer:
B) 5 and 13/15 servings
Step-by-step explanation:
Divide 8 4/5 by 1 1/2 to get 5 and 13/15
Seeing as it is a isosceles triangle, two sides are the same length as each other.
We have been given the base, at 24cm, the two other sides must be the base taken away from the perimeter;
96-24 = 72
Then because the sides are of equal length, you can divide 72 by 2 to get the final length of one of the side lengths:
72/2 = 36
The side lengths are 36cm
The base length is 24 cm,
Hope this helps! :)
Answer:
1
Step-by-step explanation:
f(x) = x² + 3x
g(x) = 5x + 2
f(3) = 3² + 3 x 3
f(3) = 9 + 9
f(3) = 18
g(3) = 5(3) + 2
g(3) = 15 + 2
g(3) = 17
(f - g)(3) = 18 - 17
(f - g)(3) = 1.
