I'm going to set up an equation to find the amount of momey Elisa has, then we can check our answer

e + 2e + 2e + 5 + 2e + 5 · 3 + e + 2e = 69
Simplify:
10e + 30 = 69
Subtract 35 from each side:
10e = 39
Divide by 10 on each side
e = 3.9

We can check our answer by putting the value in the simplified equation.
10 · 3.9 + 30 = 69
Yep! The equation is correct. Now for the answer.

Elisa
3.9
Jacob
7.8
Sandra
12.8
Damian
38.4
Martin
11.7

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)

No, because 30.4+84.6+66=181
the sum of a triangle=180
so they are not similar.

Write an equation of the line in standard form.
Andreyy89

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

-hope this helped
