PLZ HELP!!<br> Solve by substitution<br> y = -5x<br> y + 4x = -1<br> Explain PLZ
Nataliya [291]

Answer:

x= 1

Step-by-step explanation:

The value of y = -5x

Plug it in the equation of y + 4x = -1

So it becomes, -5x + 4x = -1

Combine like terms which are -5x and 4x which equals to -x

Eliminate the negative sign because x cannot be negative. Apply that to -1. It becomes 1.

Hope you find this helpful!

A bank loaned out $30,000, part of it at the rate of 15% annual interest, and the rest at 10% annual interest. The total interes
marta [7]

Answer:

x represent the value loaned at 15% and y represent the value loaned at 10%.

x=11000 and y=19000

Step-by-step explanation:

We are going to write a system of two linear equations. The first equation  will represent the total amount loaned.

x+y=30000

Now the second equation are will represent the interest earned for both loans.

(x*0.15)+(y*0.10)=3550

Then x represent the value loaned at 15% and y represent the value loaned at 10%. Now solving the equation system we have:

x=30000-y using this in the other equation to find y

((30000-y)0.15)+(0.10*y)=3550

4500-0.15y+0.10y=3550

4500-0.05y=3550

4500-3550=0.05y

950=0.05y

\frac{950}{0.05}=y

19000=y

With the value of y we can find x

x=30000-19000

x=11000

A baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold. How many muffins were sold by noon?
hodyreva [135]

Answer:

27 muffins.

Step-by-step explanation:

We have been given that a baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold.

To find the number of muffins sold by noon let us find 45% of 60.

\text{The number of muffins sold by noon}=\frac{45}{100}\times 60

\text{The number of muffins sold by noon}=0.45\times 60

\text{The number of muffins sold by noon}=27

Therefore, 27 muffins were sold by noon.
