It would be number 3 If I am correct that says 2 5/8.
Here's How its done:
So we need to add 2 1/4 and 3/8 together but how do we do that if the denominator of the fractions are different.
We will have to convert them to have the same denominator.
Since most of the answers on the screen show that they have a denominator of 8 we will convert this to also have a denominator of 8.
One of the fraction already has a denominator of 8 so we will only have to convert 2 1/4.
2 1/4 = 2 2/8
2 2/8+3/8=2 5/8
Hope This Helps

1 7/8
She ate 3/8 quarts of soup.
There are 2 1/4 quarts of soup.
So in order to solve it, you must make both denominators equal.
The GCF is 8, so 4×2=8
You must do the same with the nominator as well.
So, 1×2=2
Since 3/8 is bigger than 2/8, you must use a whole number. Lets take one.
It then becomes 1 10/8.
1 10/8 - 3/8= 1 7/8

Therefore, the answer is 1 7/8

URGENT: Create a linear system whose ONLY SOLUTION is (3,13) . I just need the equations for f(x)=? , G(x)=? To get (3,13). ASAP

Otrada [13]

The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13

The two lines can be anything as long as they give this solution

For example, if you wrote x + y = 16 (you know their values already)

Then write another y - x = 10

From here you have your equations, turn them into the f(x) form.

x + y = 16 can be turned into y = 16 - x which is f(x)=16-x

y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x

I need help with #39-42, please explain.

shusha [124]

For question 39 & 40, we need to use the below equation to complete the sentence

$l=m\sqrt{n}$

Question 39:

When ' n ' increase, the $\sqrt{n}$ will also increase and that multiplied with constant ' m ', the l will also increase.

Solution for question 39:

As $n$ increases and $m$ stays constant , $l$ increases

-------

Question 40:

Solving the equation for m, we get

$l = m\sqrt{n} \\ \\ m=\frac{l}{\sqrt{n}}$

When ' l ' increases, the numerator increase, the denominator stays constant because 'n' stays constant, for this condition, the fraction increases.

Solution for question 40:

As $l$ increase and $n$ stays constant, $m$ increases

------

For question 41 & 42, we need to use the below equation to complete the sentence

$r=s^2/t^2$

Question 41:

When $s$ is triped, the equation will be...

$r=(3s)^2/t^2=\frac{3^{2}s^{2}}{t^2} =9s^2/t^2$

Solution for question 41:

If $s$ is tripled and $t$ stays constant, $r$ is multiplied by 9

--------

Question 42:

When t is doubled, the equation will be...

$r=s^2/(2t)^2=\frac{s^2}{2^2 \cdot t^2}=\frac{s^2}{4t^2}\\ \\ r=0.25s^2/t^2 \; \; (or) \; \; \frac{1}{4} \cdot \frac{s^2}{t^2}$

Solution for 42:

If $t$ doubled and $s$ stays constant, $r$ is multiplied by 1/4 or 0.25

Write the equation in slope-intercept form y+3=4(x−1) plz do step by step

Rainbow [258]

Answer:y=4x -7

Step-by-step explanation:

The slope intercept form is: y= mx + b

Y+3 = 4(x-1) step one distribute 4

Y+3= 4x - 4 step two subtract 3 from both sides

Y=4x -7
