Let hamburger = fries + 50
2hamburger + 3fries = 1700 **Given**
2(fries+50) + 3fries = 1700
2fries + 100 + 3fries = 1700
5fries = 1600
fries = 320
hamburger = 320 + 50
hamburger = 370 cal
Answer:
There would be 350 girls in the school.
Step-by-step explanation:
We can find this by creating two proportions. the first fraction would be the number of girls out in the sample:
7/12
The second part would be the amount of girls in the whole school. We can set the girls as x since we do not know.
x/600
Now we can set the two equal to each other and cross multiply.
7/12 = x/600
600*7 = 12*x
4200 = 12x
350 = x
Answer:
3
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(- 2, - 6) and (x₂, y₂ ) = D(4, - 3)
CD =
