Answer:

x=7

Step-by-step explanation:

AC=3x+3  AB=-1+2x and BC=11

AC = AB + BC

ALL THE STEPS:

3 X + 3 = - 1 + 2 X + 11

3 X + 3 = 2 X + 10

3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10

X + 3 = 10

X + 3 + ( - 3 ) = 10 + ( - 3 )

X = 7

I really need help :(
zavuch27 [327]

Answer:

Amira used 4 balloons for each balloon animal.

Step-by-step explanation:

From the table, we can conclude that:

For 20 animals being sold by her,  the leftover balloons were 180.

Then there is an increase in the number of animals being sold. She now sells 29 animals. So, the increase in animals being sold is given as:

29 - 20 = 9.

So, 9 more animals were sold. The balloons used for these 9 animals can be obtained by taking the difference of the leftover balloons for the two days.

The difference of the leftover balloons = 180 - 144 = 36.

So, 36 balloons were used for selling 9 more animals.

Similarly, there is an increase of another 9 animals when 38 animals were sold as 38 - 29 = 9. Also, the balloons used in this case is 36 only as the difference of the leftover balloons is 36.

144 - 108 = 36

Therefore, we conclude that for selling 9 balloon animals, Amira used 36 balloons.

Number of balloons used for 9 balloon animals = 36

∴ Number of balloons used for 1 balloon animal = \dfrac{36}{9}=4 (Unitary method)

Thus, Amira used 4 balloons for each balloon animal.

Find the volume of the prism.
stiks02 [169]

Answer:

1760 cm³

Step-by-step explanation:

Volume For top "trapezoidal" prism : (14 * 4)/2 * 20 = 28 * 20 = 560

Volume for bottom rectangular prism = 6 x 10 x 20 = 60 x 20 = 1200

1200 + 560 = 1760 cm³

If my answer is incorrect, pls correct me!

Write an equation in point-slope form of the line through point J(-8,10) with slope -5.
mafiozo [28]
Point-slope form is y - y1 = m(x - x1). If you apply that point and the slope to the formula (hence the name point-slope), you'd get y - 10 = -5(x + 8).

Hope this helps! :)

REVISE: I accidently put y instead of x in the -5(x + 8) part. It's fixed now.
