Can y'all please help.
sattari [20]

Answer:

See explanation

Step-by-step explanation:

<u>Step 1.</u> Substitute for d to solve for n:

From the first equation:

d=70-n

Then substitute it into the second equation:

0.1(70-n)+0.05n=5.5\\ \\7-0.1n+0.05n=5.5\\ \\7+(-0.05n)=5.5\\ \\-0.05n=5.5-7=-1.5\\ \\n=\dfrac{-1.5}{-0.05}=30

<u>Step 2:</u> Substitute for n to solve for d:

d+n=70\\ \\d+30=70\\ \\d=70-30=40

The line represented by the equation 3x + 5y = 2 has a slope of -3/5 . Which shows the graph of this equation?
erica [24]
What exactly is being asked? the slope is easy as all you have to do is move the 3x over so that 5y = -3x + 2 
divide by 5 and you get y = -3/5x +0.4
that's the equation of the graph if that's what is being asked

Michael is making cookies. Each batch uses 2 cups of flour. He plans to use less than 30 cups of flour so that he has enough lef
Elan Coil [88]
Your answer is A. Michael can make fewer than 13 batches of cookies

If he has 30 cups of flour and has already used 4, subtract.
=26
so he has 26 cups of flour and it takes two cups to each batch, so divide.
26/2=13
if the two batches he has already made are included in the problem, then your answer would actually be C. but I don't think that's the case.
