Solve the system by substitution.
y = 5x
y = 9x + 4

Answers

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)

Lorenzo ate 25 of his bag of almonds. His 4 friends ate equal shares of the remaining bag of almonds. Which expression represents the almonds that each friend ate?

Answers

Answer:

(x - 25) / 4

Step-by-step explanation:

In this scenario, we have one unknown variable which is the total of the bag of almonds, therefore we can represent this with the variable x. Since Lorenzo ate 25 of this bag we would need to subtract this from the total of the bag. Then we need to divide the remainder by 4 since each of his friends ate the rest in equal parts. This would leave us with the following expression ...

(x - 25) / 4

The ratio of the measure of the three angles of a triangle is 3:4:8. Find the mesure of the large angle

Answers

Answer:

96°

Step-by-step explanation:

Ratio of angles :

3 : 4 : 8

Sum of angles in a triangle = 180°

The value of the largest angle = angle with the largest ratio

This is the value of the angle with ratio 8

Sum of ratio : (3 + 4 + 8) = 15

Hence,

(8 / 15) * 180°

(8 * 180°) / 15

1440 / 15

= 96°

4y = 8

y = 2

(5, 2)

In the figure below, m_1=(x-9° and m2 =6xº.
Find the angle measures.
Help!!!!

Answers

Answer:

(x-9)°+6x=180°[by linear pair]

7x-9=180°

7x=180°+9

7x=189°

x=189/7

x=27

(x-9)°=27-9=18°

(6x)°=6×27=162°

The angle measures are 18 degrees and 162 degrees.

What is Angle?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

In the given figure ∠1=x-9 and ∠2=6x

The sum of ∠1 and ∠2 is 180 degrees by linear pair.

∠1 +∠2 =180

x-9+6x=180

Add the x variable terms

5x-9=180

Add 9 on both sides

5x=189

Divide both sides by 5

x=27

Now substitute value of x in angle 1 and angle 2.

∠1=x-9=27-9=18 degrees

∠2=6x=6(27)=162 degrees.

Hence, the angle measures are 18 degrees and 162 degrees.

16 ÷ 22 + (6 x 2) - 8

Answers

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72
16 ÷ 22 + (6 x 2) - 8 = 4.72
