Answer:

3.2

Step-by-step explanation:

ABCD and JKLM are similar. To find the x, first find the ratio for all of the sides.

AD and JM are similar --> 2.4 / 3 = 0.8

BC and KL are similar --> 4 / 5 = 0.8

DC and ML are similar --> 2.4 / 3 = 0.8

AB and JK are similar --> 4 × 0.8 = 3.2

Hope this helps, thank you :) !!

A pair of shoes usually sells for $61. If the shoes are 40% off, and sales tax is 5%, what is the total price of the shoes, incl

lyudmila [28]

Since sale is 40% so the price is 60%

61*(60%) = 36.6

the tax is 5%

so the price after tax is: 36.6 * (1 +5%) = $38.43

What is the solution to this equation? <br> 3x-x+8+5x-2=10

Kaylis [27]

3x - x + 8 + 5x - 2 = 10

combine like terms on the left, then add or subtract as asked
(3x - x + 5x) + (8 - 2) = 10

7x + 6 = 10
subtract 6 from both sides

7x = 4
divide both sides by 7

x = 4/7

Hope this helps! :)

Answer as many as you can please (write in slope-intercept form)

RoseWind [281]

Answer: See below

Step-by-step explanation:

For the first one, we are already given our slope. All we need to do is find the y-intercept, b.

y=-2x+b

6=-2(-3)+b

6=6+b

b=0

The slope-intercept form is y=-2x.

For the second one, we need to first find the slope using $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ .

$m=\frac{1-13}{3-(-6)} =\frac{-12}{9}$

Now that we have our slope, we can plug it into our slope-intercept form to solve for b.

$y=-\frac{12}{9} x+b$

$3=-\frac{12}{9}(1)+b$

$-\frac{9}{4} =b$

The slope-intercept form is $y=-\frac{12}{9} -\frac{9}{4}$ .

For the third one, we are already given the slope, so all we have to do is find b.

$y=-\frac{1}{2}x +b$

$-7=-\frac{1}{2} (-4)+b$

$-7=2+b$

$-9=b$

The slope-intercept form is $y=-\frac{1}{2} x-9$ .

For the last one, we need to first find the slope using $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ .

$m=\frac{-8-2}{3-1}=\frac{-10}{2} =-5$

Now that we have our slope, we can plug it into our slope-intercept form and find b.

$y=-5x+b$

$2=-5(1)+b$

$2=-5+b$

$7=b$

Our slope-intercept form is $y=-5x+7$ .
