Answer:

20+7x

Step-by-step explanation:

you'd multiply 2 by 5 and 2 by 3x which will give you 10+ 6x; Then add the others : 2(5+3x)+(x+10) would be 10+6x+x+10 so its 20+7x.     .

Answer: 30+4x or 2(15+2x)

Step-by-step explanation:

So the way you would do this is actually kinda simple.

You question is 2(5+3x)+(x+10)

First you wanna add the common number together. So you would change you problem to

2(5+10)+(x+3x)

Now you want to start by solving 2(5+10)

The two on the outside means you multiply so you would do

2x5+2x10 you would get the answer 10+20=30

Now you’re equation is 30+(x+3x)

So now you need to do (x+3x) in this case we would make X=1

So you do 1+3(1) or 1+(3x1) And you get 4x

Now you have the answer 30+4x or to siplfy it you get 2(15+2x)

Hope this helps you xoxo

If 100 pencils can be sold for $90, then how many pencils are needed to earn $8500?
ira [324]

Step-by-step explanation:

You can set up a proportion.

Let x be the number of pencils needed.

\frac{100}{90} = \frac{x}{8500}

Solve for x.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)

What is an equation of a line,in point-slope from, that passes through (1, -7) and has a slope of -2/3
il63 [147K]

Answer:

y + 7 = - \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

Where m is the slope and (a, b) a point on the line

Here m = - \frac{2}{3} and (a, b) = (1, - 7), thus

y - (- 7) = - \frac{2}{3}(x - 1), that is

y + 7 = - \frac{2}{3}(x - 1) ← in point- slope form

Find k so that the distance from (–1, 1) to (2, k) is 5 units. k= k= *there are two solutions for 2*
dalvyx [7]

Answer:

k = -3

k =5

Step-by-step explanation:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d = 5\\(-1,1) =(x_1,y_1)\\(2,k)=(x_2,y_2)\\

5=\sqrt{\left(2-\left(-1\right)\right)^2+\left(k-1\right)^2}\\\\\mathrm{Square\:both\:sides}:\quad 25=k^2-2k+10\\25=k^2-2k+10\\\\\mathrm{Solve\:}\:25=k^2-2k+10:\\k^2-2k+10=25\\\\\mathrm{Subtract\:}25\mathrm{\:from\:both\:sides}\\k^2-2k+10-25=25-25\\k^2-2k-15=0\\\\\mathrm{Solve\:by\:factoring}\\\\\mathrm{Factor\:}k^2-2k-15:\quad \left(k+3\right)\left(k-5\right)\\\mathrm{Solve\:}\:k+3=0:\quad k=-3\\

\mathrm{Solve\:}\:k-5=0:\quad k=5\\\\k =5 , k=-3
