HELP ME PLEASE!!!!!!!!!!!!!!!!!!!!Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms? y = 2x 2x + 3y = 16
A. 8x = 16
B. 4x = 16
C. 5x = 16
D. 5y = 16

This is my answer
Answer 2
Answer:

Final answer:

By substituting y = 2x into the second equation and combining like terms, we get the equation 8x = 16.

Explanation:

This question is from the field of Algebra. You are asked to substitute the first equation into the second equation, then simplify by combining like terms. Substituting y = 2x from the first equation into the second equation 2x + 3y = 16, we replace y with 2x, thus transforming the second equation into 2x + 3(2x) = 16. Distributing the 3 to the 2x within the parentheses gives us 2x + 6x = 16. By combining the like terms on the left side, we get 8x = 16 which is option A.

Answers

The ratio of the smaller to the larger is 3:9.  That can also be written as a fraction, (3)/(9), which of course can be reduced to (1)/(3) or 1:3.  That's your ratio.

Step-by-step explanation:

we need to first find the area

4.5 x 4 = 18

1.5 x 2 = 3

18 - 3 = 15

15/2.25 = 20/3

20/3 is 6.666666666666666666666666666666.....

4. Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place.18.729

Answers

Answer:

Hence, the estimate value of  9.327 + 5.72 + 4.132 to one decimal place is:

 19.2

Step-by-step explanation:

We have to Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place

We find the sum of these numbers:

Sum=  9.327+5.72+4.132

      =  19.179

Now we have to estimate the value to one decimal place

  so, on approximating the value, we get the sum=19.2

Hence, the estimate value of  9.327 + 5.72 + 4.132 to one decimal place is:

19.2
The sum for those numbers is 19.179 NOT 18.729. HOWEVER the Estimation of the sum and the answer for this question is 19.2 because the decimal place you are finding has a number to its right that is greater to that decimal place so you add the one to the decimal place you are finding.

Hi Scotti


0>3x-3-6

0>3x-9

Now flip

3x-9<0

We need to add 9 to both sides

3x-9+9<0+9

3x<9

Divide both sides by 3 so we can find the value for x

3x/3<9/3

x<3


I hope that's help :)
