Answer:

10.5, 10\frac{1}{2}, or \frac{21}{2}

Step-by-step explanation:

To solve, you can use a variable (x) to represent the width.

The equation for area is A=L×W

So the Area is 820 and the length is 78.

820= 78w

Isolate the variable to solve.

w=10.5128....

If you round, it will be 10.5

10.5 as a fraction is 10\frac{1}{2} or \frac{21}{2}

Find the x-intercept of the line whose equation is 8x + 2y = 4.<br> 04<br> 02<br> 1/2
bezimeni [28]

Answer:

1/2

Step-by-step explanation:

The x-intercept is a point on the graph that is located on any point of x but must have a y-value of 0. To find the x-intercept, we must set y in the given equation equal to 0.

8x + 2y = 4

8x + 2(0) = 4

8x = 4

x = 4/8

x = 1/2

Betty saves $161 a month. She saves $141 less each month than Jack. How much will jack save in 2 years?
tresset_1 [31]

Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.

First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.

141 + 161 = 302

Now, that we know how much Jack saves per month.

Then, we have to find out how many months are in 2 years.

We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.

12 x 2 = 24

Therefore, there are 24 months in two years.

Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.

24 x 302 = 7,248

Thus, Jack will save approximately $7,248 in 2 years.

ruslelena [56]

The surface area of the cube with a side length of 2 units is 24 units squared

<h3>How to determine the surface area?</h3>

The side length of the cube is given as:

l = 2

The surface area is calculated as:

Surface area = 6l^2

This gives

Surface area = 6 *2^2

Evaluate

Surface area = 24

Hence, the surface area of the cube is 24 unit squared

Write the multiplicative inverse of <br>a) -13/19​
irga5000 [103]

Answer:

-  \frac{19}{13}

Step-by-step explanation:

the \: multiplicative \: inverse \: of \:  \\  -  \frac{13}{19}  =  -  \frac{19}{13}

Product of a number and its multiplicative inverse should be equal to 1.

So,

\bigg ( -  \frac{13}{19} \bigg)  \bigg ( -  \frac{19}{13} \bigg)

= \frac{13}{19}\times  \frac{19}{13}

=1
