From the second equation we can find that d=43-(9/10)*n
we can put this equation into the first one,
So we have equation 60(43-(9/10)*n)+65n=2800
Solving that we get n=20
60d+65*20=2800
d=25
So the answer is d=25 and n=20
B there is inf. many solutions:
2x-4y=8 is y = 1/2x - 2
8x-16y=32 is y = 1/2x - 2
Hello!
"Lexi wants to share the sheet of tiger stickers with two friends are there enough stickers to make equal shares for lexi and her two friends"
So there's only 1 sheet of stickers so there's not really enough to share with 2 friends because there's only one sheet which means however many is on the sheet won't be an equal amount to share amongest 3 people.
Hope this helps!

Heron’s formula is useful when we know all three sides of triangle
Answer:
The answer is 50 hours
Step-by-step explanation:
4x = 200
Divide both sides by 4
x = 200 \div 4 = 50
so after 50 hours of walking, the men will be 200 miles apart.
