Answers

Answer 1
number 4. .75/.4=1.875
Answer 2

Answer:

1 and 7/8

Step-by-step explanation:

[tex]\frac{3}{4}[/tex] ÷ [tex]\frac{2}{5}[/tex]

When dividing you have to flip the second number. When the fraction/number flips the problem will turn into multiplication.

[tex]\frac{3}{4}[/tex] × [tex]\frac{5}{2}[/tex]

Now just multiply them. 3×5 and 4×2

[tex]\frac{15}{8}[/tex]

Simplify the fraction

[tex]1\frac{7}{8}[/tex]

I hope this helps!

5x+3y=18 and 3x-3y=15 solve for y and x using elimination method

Answers

Answer:

x = 4.125 or [tex]4\frac{1}{8}[/tex]

y = -0.875 or [tex]-\frac{7}{8}[/tex]

Step-by-step explanation:

5x + 3y = 18

3x - 3y = 15

3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.

8x = 33

x = 4.125

Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.

3(4.125) - 3y = 15

12.375 - 3y = 15

-3y = 2.625

y = -0.875

Now we know what y is.  I hope this helps :)

Answer:

29.25

Step-by-step explanation:

This is a simple function table we are working with, so we see that 2 (pounds) would cost around $4.50. So Next we look at 4 would equal $9. By doing this I divide 9 by 4 to get the answer of 2.25. This is are new function table rule of C=P x 2.25. Now that we have this we know that 13 is are P (pounds) and we are looking for are C (cost) After we input 13 into are function rule. We get the answer of $29.25.

Answer:  well 14 pounds cost $31.50

so that means 13 pounds cost $29.50

Step-by-step explanation:

Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?

The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.

[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]

We already have an equal denominator so we can just subtract.

[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]

Kip has [tex]\frac{5}{6}[/tex] pounds left.
