A test is worth 50 points. Multiple-choice questions are worth 1 point, and
short-answer questions are worth 3 points. If the test has 20 questions, how
many multiple-choice questions are there?
A. m + s = 50
B. m + 2s = 20
C. m.s= 20
D. m + s = 20

Answers

Answer 1

Answer:

d) m + s = 20

m = 5

Step-by-step explanation:

m + 3s = 50

m + s = 20

m + 3(20-m) = 50

m + 60 - 3m = 50

60 - 2m = 50

60 = 50 + 2m

60 - 50 = 2m

10 = 2m

5 = m

Answers

Answer:

x = [tex]\frac{ab}{b+a}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{a}[/tex] + [tex]\frac{1}{b}[/tex] = [tex]\frac{1}{x}[/tex] ( express the sum on the left as a single fraction )

[tex]\frac{b+a}{ab}[/tex] = [tex]\frac{1}{x}[/tex] ( cross- multiply )

x(b + a) = ab ← divide both sides by (b + a)

x = [tex]\frac{ab}{b+a}[/tex]

What is an equation of the line that passes through the point
(-6, -2) and is parallel to the line 3x – 2y = 2?

Answers

Answer: y=3/2x+7

Step-by-step explanation:

To find the equation of the line that passes through the given point, let's first convert the given equation to slope-intercept form.

3x-2y=2           [subtract both sides by 3x]

-2y=-3x+2        [divide both sides by -2]

y=3/2x-1

Now that we have the equation in slope-intercept form, we know that the slope must stay the same because parallel lines NEVER touch. All we have to do is plug in the given point to find the y-intercept.

-2=3/2(-6)+b    [multiply]

-2=-9+b            [add both sides by 9]

b=7

Now, we know that the parallel equation is y=3/2x+7.

u= 6x-35/w Hope this helped <3

Step-by-step explanation:

Let's solve for u.

uw=6x−35

Step 1: Divide both sides by w.

Step-by-step explanation:

Answer:-

This all will be attempted according to Figure.

We can see in figure ,

[tex]\tt{UW = 4x-20+19}[/tex] _____(1)

Now, question says that:-

[tex]\tt{UW = 6x - 35}[/tex]_______(2)

Equating ,

(1)=(2)

So,

[tex]\tt{4x-20+19 = 6x - 35}[/tex]

[tex]\tt{4x-1 = 6x - 35}[/tex]

[tex]\tt{4x-6x = +1- 35}[/tex]

[tex]\tt{-2x = -34}[/tex]

[tex]\tt{x = \dfrac{34}{2}}[/tex]

[tex]\tt{x = 17}[/tex]

Now, we need UW.

Placing it in any Equation, Let me take (2),

6(17) -35

= 102 - 35

So, 67 is the answer.

Hope it helps :)

Find the value of each variable and the measure of each labeled angle 1-3

Answers

Answer:

1.) x = 30 ; 150°   2.) x = 30 ; 50°  3.) x = 40 ; 122°

Step-by-step explanation:

Each one of the problems revolves around vertical angles. Verticle angles are equal to each other.

1.)

5x = 3x + 60

2x = 60 (Subtracted 3x on both sides.)

x = 30 (Divided 2 on both sides.)

Know that we know the variable's value, time to find the angles.

5(30) = 3(30) + 60

150 = 150

This means the angles are 150°.

2.)

3x - 40 = x + 20

2x - 40 = 20

2x = 60

x = 30

3(30) - 40 = (30) + 20

90 - 40 = 50

50 = 50

This means the angles are 50°.

3.)

5x - 78 = 3x + 2

2x - 78 = 2

2x = 80

x = 40

5(40) - 78 = 3(40) + 2

122 = 122

This means the angles are 122°.

The value of x is 30° and the unknown angle is 150°.

We need to find the unknown angles from the given figure.

What are vertically opposite angles?

The vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

From figure 1:

(5x)°=(3x+60)°

⇒5x-3x=60

⇒2x=60

⇒x=30

So, (5x)°=(3x+60)°=150°

From figure 2:

(3x-40)°=(x+20)°

⇒3x-x=60

⇒2x=60

⇒x=30

So, (3x-40)°=(x+20)°=50°

From figure 3:

(3x+2)°=(5x-78)°

⇒5x-3x=78+2

⇒2x=80

⇒x=40

So, (3x+2)°=(5x-78)°=122°

Therefore, the value of x is 30° and the unknown angle is 150°.
