Answer:

Part 1 is 420-10 and 210-5, part 2 is 200-10, and 300-15, etc.

Step-by-step explanation:

If this is what I think it is then you're just going to want to divide the first number by the second then once you get all four answers for each part you'll be able to see which ones match. Such as in part 1 you have:

340 and 20 which divides to get 17

420 and 10 which divides to get 42

450 and 30 which divides to get 15

210 and 4 which divides to get 42

Since the second and fourth row both have solutions of 42 they both have equivalent rates.

Hopefully this is what that assignment is asking!

Solve the equation using the distributive property and properties ofequally 1/2 (x+6)=18 what is the value of X
Natali [406]

x = 30

The distributive property says that we need to multiply what's in the brackets by 1/2 (so 1/2*x and 1/2*6) to get the equation 1/2x + 3 = 18.

Then we need to subtract our constant, 3, from boths sides to get 1/2x = 15.

Multiply both sides by two to isolate x and you get x = 30.

Hope this helps! :)

4n^(2)+4n=3<br> Please help with the work
Kaylis [27]

Answer:

n= 1/2 ( \frac{1}{2} )  or  (0.5)

AND

n= -3/2 ( -\frac{3}{2} ) or (-1.5)

Step-by-step explanation:

4n^2+4n=3

step1: move 3 to the other side and make the equation equal to zero.

4n^2+4n-3=0

step2: factorise the equation.

(2n-1)(2n+3)=0

step3: make each bracket equal to zero.

2n-1=0

2n+3=0

step4: solve for n values.

<u>1.</u> 2n-1=0

(add 1 for both sides)

2n=1

(divide by 2 for both sides)

n= 1/2 ( \frac{1}{2} )  or  (0.5)

<u>2.</u> 2n+3=0

( subtract 3 for both sides)

2n=-3

(divide by 2 for both sides)

n= -3/2 ( -\frac{3}{2} ) or (-1.5)

D, because all of the others when multiplied are greater or less than 34. If you multiply the sides of D you get 34 exactly.
