Answer:

x = -172

Step-by-step explanation:

x + y = -11 and 161 - y = 0

hence using elimination method :

161 + x = -11

x = -11 - 161

x = - 172

Can someone help pls

Answer:

Slope = 4/3

Step-by-step explanation:

Formula for slope-intercept form: y=mx + b

Given: 3y - 4x = -6

Add -4x to the right hand side to isolate out 3y (y).

It should look like this: 3y = 4x -6

Now divide both sides by 3.

You should get: y = 4/3x -2

Since it's asking for slope, your slope is 4/3.

Kelly has 50% more money than Luis. Luis has $40. If Luis gets $8 more, will Kelly still have more money than Luis? What percent

OverLord2011 [107]

Answer:

Kelly will still have more money than Luis

Kelly will have 25% more

Step-by-step explanation:

Let x represent the amount of money Kelly has and y, Luis

Luis has $40

and Kelly has 50% more money than Luis

Therefore, Kelly has;

50% of $40 + $40

= 0.5*40 + 40

= $60

If Luis gets $8 more, Luis will have;

$8 + $40 = $48

since Luis' $48 is less than Kelly's $60, Kelly will still have more money than Luis

Difference in their money = $60 - $48 = $12

Therefore, Kelly will have;

12/48 * 100 more than Luis

= 25% more

Answer:

$6\pi$

Step-by-step explanation:

The area of the circumference of a circle is:

$C=2\pi r$

We know that r is 8, so we can plug that into the formula.

However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).

$C = (\frac{3\pi/4}{2\pi})*(2\pi *8)\\C = (\frac{3}{8})(16\pi)\\C = \frac{48\pi }{8} \\C = 6\pi$

A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What

ludmilkaskok [199]

Answer:

3 gallons

Step-by-step explanation:

Length of the rectangular wall = 23.6 feet

Width of the rectangular wall = 19.2 feet

Surface area of the wall = 23.6 × 19.2

= 453.12 square feet

∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon

∴ 1 square feet of the wall will be covered by the amount of paint = $\frac{1}{200}$ gallons

∴ 453.12 square feet will require the amount of paint = $\frac{453.12}{200}$

= 2.2656 gallons

Therefore, minimum 3 gallons will be required to paint the wall.
