Given the system of equations presented here: 3x + 5y = 29 x + 4y = 16 Which of the following actions creates an equivalent syst

em such that, when combined with the other equation, one of the variables is eliminated? (5 points) Select one: a. Multiply the second equation by −1 to get −x − 4y = −16 b. Multiply the second equation by −3 to get −3x − 12y = −48 c. Multiply the first equation by −1 to get −3x − 5y = −29 d. Multiply the first equation by −3 to get −9x − 15y = −87

It would be b. If you combine -3x-5y and 3x+5y, the x's cancel out. That would be the variable.

Name the figure below in two different ways.<br> C<br> J<br> b
Irina18 [472]

Based on the letters representing the the given figure, two different ways that it can be named are CJB and BJC.

<h3>What other ways can the figured be named?</h3><h3 />

The figure has the midpoint of J.

This means that when you are naming the figure, J has to be in the middle of either of the names that you choose.

You can therefore name the shape CJB which would mean that C is the starting point and B is the ending point.

Or you could name it BJC with B being the starting and C being the ending.

Rest of the question:

Shape description is that of a line that has three different points which are C, J, and B.

Colt1911 [192]

Answer:

After 4 more days

Step-by-step explanation:

The remaining amount of money needed to reach the goal is $200 this is because 1000-800=200

Now we divide the 200 by the amount Karen  earns a day

200/50=4

That means after 4 more days Karen will have $1000

There are two numbers whose sum is 53. Three times the smaller number is equal to 19 more than the larger number. What are the n
julsineya [31]

18 and 35. The numbers whose sum 53 are 18 and 35.

The key to solve this problem is using a system of equations.

There are two numbers whose sum is 53. This number can be represented as x and y. So:

x + y = 53

Three times the smaller number is equal to 19 more than the larger. Let's set x as the smaller number and y the larger number. So:

3x = 19 + y

Clear y in both equations and let's use the equalization method to solve for x:

y = 53 - x and y = 3x - 19

Then,

53 - x = 3x - 19

53 + 19 = 3x + x ---------> 3x + x = 53 + 19 -------> 4x = 72

x = 72/4 = 18

To find y, let's substitute x = 18 in the equation x + y = 53

18 + y = 53 --------> y = 53 - 18

y = 35

Mary is cutting strips of paper for a craft project. Each strip is 1/6 of a sheet of paper. Mary has 2/3 of a sheet of paper lef
nevsk [136]

Answer:

4 more strips

Step-by-step explanation:

Given that:

Length per strip = 1/6

Fraction of paper left = 2/3

Number of strips that can be cut from the Fraction left ;

Fraction left ÷ length per strip

2/3 ÷ 1/6

2/3 * 6/ 1

(2 * 6) / (3 * 1)

12 / 3

= 4
