Answer:

Part a) Tim has completed the greater amount of work

Part b) They have completed together \frac{142}{143} of the project or 99.3\% of the project

Step-by-step explanation:

Part a) Who has completed the greater amount of work?

we have

Jaime has 5/11 of a project completed

Tim has 7/13 of a project completed  

Multiply 5/11 by 13/13 and 7/13 by 11/11

so

Jaime ---> \frac{5}{11}(\frac{13}{13})=\frac{65}{143}

Tim ---> \frac{7}{13}(\frac{11}{11})=\frac{77}{143}

Remember that

When fractions have the same denominator, the larger fraction is the one with the larger numerator  

\frac{77}{143} >\frac{65}{143}

therefore

Tim has completed the greater amount of work

Part b)  How much of the project have they completed together?

we have that

Jaime has 65/143 of a project completed  

Tim has 77/143 of a project completed  

Sum the fraction of the project completed by Jaime plus the fraction of the project completed by Tim

\frac{65}{143}+\frac{77}{143}=\frac{142}{143}

Convert to percentage

Multiply by 100

\frac{142}{143}(100)=99.3\%

Can someone please professionally explain the math equations below. (Not just answer the question)
Rus_ich [418]

Step-by-step explanation:

We will solve this system of equations using two methods: elimination and substitution.

Method 1: Elimination

2x - y = -8. #1

-5x + y = 26. #2

Note that by adding these two equations, the y-variable is eliminated (thus the name) and you're only left with an equation with one variable. So upon adding, we get

-3x = 18 or x = -6

Using this value for x, put this back in either one of the equations. Let's use the 2nd one.

-5(-6) + y = 26

--> 30 + y = 26

Moving 30 to the right side, we get y = -4.

Method 2: Substitution

This is done by isolating one variable to the left side in one equation and then using it on the other equation. Let's take equation #2 and put the y-variable on the left side and you should get

y = 5x + 26

Now use this equation and plug it into the y in equation #1:

2x - (5x + 26) = -8

--> 2x - 5x - 26 = -8

--> -3x = 26 - 8 = 18 or <u>x</u><u> </u><u>=</u><u> </u><u>-</u><u>6</u><u>.</u>

Use this value for x into either one of the equations. Let's use equation #1 this time.

2(-6) - y = -8

--> -12 + 8 = y or <u>y</u><u> </u><u>=</u><u> </u><u>-4</u><u>.</u>

Notice that using either method will give you the same result, as one might expect.

DIA [1.3K]

Answer:

She can make cookies for 4.95 weeks

Step-by-step explanation:

2 x 1 2/3 = 3.333333333

16.5/ 3.333333333 = 4.95

Since Jordan is making two batches of Cookies per week, you need to multiply 2 by the amount of resources needed to bake one batch of cookies. So you multiply 1 and 2/3 by 2 to get the amount of resources neccesary for one week of making cookies. Then, you take the full amount of resources that she has, and divide that by the amount she uses per week, that number will give you the number needed to figure out how many weeks she has to bake cookies.

To figure out the number that is being divided to get the whole number in weeks, you would take the 16.5 cups of flour. The reason why this is, is because that Is the starting number of cups that she has. So here you would need to divide the amount you are taking from it each week. This will result in the amount of weeks that she is able to bake cookies with her flour.
