Answer:

x = 6, ∠ B = 126°

Step-by-step explanation:

∠ A and ∠ B are alternate angles and congruent, so

8x + 78 = 2x + 114 ( subtract 2x from both sides )

6x + 78 = 114 ( subtract 78 from both sides )

6x = 36 ( divide both sides by 6 )

x = 6

Then

∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°

Which expression is equivalent to (10 +7r−r2)+(−6r2−18+5r)

Answers

Answer: -7r^2+12r-8
Explanation;
1. Combine -r^2 and -6r^2 to get -7r^2
2. Subtract 18 from 10 to get -8
3. Combine 7r and 5r to get 12r

The expression is equivalent to [tex]-7r^{2} + 12 r -8[/tex].

Here,

The expression is,

[tex](10 + 7r -r^{2} ) + (-6r^{2} -18+5r)[/tex]

We have to simplify this expression.

What is Quadratic equation?

Quadratics can be defined as a polynomial equation of a second degree.

Now,

The expression is,

[tex](10 + 7r -r^{2} ) + (-6r^{2} -18+5r)[/tex]

By simplify, we get;

[tex](10 + 7r -r^{2} ) + (-6r^{2} -18+5r)[/tex]

[tex]10 + 7r -r^{2} -6r^{2} -18+5r[/tex]

[tex]10 -18 + 7r +5r -r^{2} -6r^{2}[/tex]

[tex]-7r^{2} + 12 r -8[/tex]

Hence, The expression is equivalent to [tex]-7r^{2} + 12 r -8[/tex].

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 8 large boxes and 4 small boxes has a total weight of 209 kilograms. A delivery of 3 large boxes and 2 small boxes has a total weight of 86 kilograms. How much does each type of box weigh?

Answers

Answer: (s for small, l for large) s=15.25 kg, l=18.5 kg.


Explanation: We need a system of equation to find the two weights of both boxes.
We can use 4s+8l=209 and 2s+3l=86.

If we multiply the second equation by -2 (for elimination), we will have -4s-6l=-172.

Combing the first equation with this new one gives us 2l=37, where dividing by 2 gives us l=18.5 kg.

We can plug 18.5 into any of the two original equations to find s.

4s+8*18.5=209
4s+148=209
4s=61
s=15.25 kg

The length of the hypotenuse (x) is an irrational number between 6 and 8. Both legs have measured that are whole numbers. What is one possible set of measures for the sides of the right triangle

HELP ME PLEASE !

Answers

Step-by-step explanation:

Since 6 < x < 8, we have 36 < x² < 48.

Let a and b be the sides of the right triangle.

a²/b² could be 1², 2², 3², 4², 5² and so on.

A possible set of measures is 6 and 2.

This will give x² = 6² + 2² = 40, x = √40 which is irrational.

Answer:

Amount of white paint used to paint bedroom walls = [tex]1.96[/tex] pints

Step-by-step explanation:

Total amount of blue paint and white paint = 9.8 pints

Amount of blue paint used to paint bedroom walls = [tex]\frac{4}{5}[/tex]

Amount of white paint used to paint bedroom walls = [tex]1-\frac{4}{5}=\frac{1}{5}[/tex]
