Answer: 30 students liked both.

step-by-step explanation: If there are 65 students and 10 liked math but not english you subtract 10 from 65, you get 55. You continue to the next one, 55-20= 35, now there are 35 students but 5 of those students don't like either, so 35-5=30, meaning there are 30 students that like both english and math. I hope this helps.

Answer:

The answer is B.) Inductive Reasoning

Step-by-step explanation:

Deductive reasoning requires one to start with a few general ideas, called premises, and apply  them to a specific situation. Recognized rules, laws, theories, and other widely accepted truths  are used to prove that a conclusion is right.

Answer:

The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)

Step-by-step explanation:

Remember that all triangles have a full measurement of 180 degees.

Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.

Now we subtract 180 - 133 = 47.

The measure of angle two is 47 degrees.

Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.

180 - 138 = 42.

Answer:

the answer is 20 .put the 5 in place of x                                                                          

and u always remember that f(5) =f(x)

Step-by-step explanation:

Answer:

x<7

I Believe

Answer:

I pretty sure the answer is ASA, I hope it's right!

Sum of three angles in the triangle equals to 180.

70+30+x=180

100+x=180

x=180-100

x=80

Therefore, the answer is 80.

Answer:

1.) yes

2.) no

Step-by-step explanation:

1.) Yes

3x - 2y = 1

3(5) - 2(7) = 1

15 - 14 = 1

1 = 1

2.) No

2x + 8y = 26

2(-3) + 8(-4) = 26

-6 - 32 = 26

-38 ≠ 26

Answer:

1. yes 2. no

Step-by-step explanation:

1. 3(5)-2(7)=1 √

2. 2(-3)+8(-4)=-38 not 26 ×

Answer:

The answer is C.

explanation:

The reason for answer (C) is because when looking for a function the (X) value cant repeat, but the (Y) can. In answer (C) the x-value 19 repeats.

sorry if its wrong, but pretty sure im right.

Answer: They are equivalent

Step-by-step explanation:

Here is the complete question:

18 vocabulary words learbed in 2 hours 27 vocabulary words learned in 3 hours Are they equivalent? Why

From the question, we are informed that 18 vocabulary words are learned in 2 hours. The number of words learned per hour will be:

= 18/2

= 9 words per hour.

27 vocabulary words learned in 3 hours. The number of words learned per hour will be:

= 27/3

= 9 words per hour.

Since they both have identical number of words learned per hour, it means that they're equivalent.

Answer:

The speed in the first part is 16 mph.

Step by step explanation:

The total distance is 48 miles. The total time is 4 hours.

In the second part of the trip, he was traveling at speed s for distance d for 2 hours.

In the first part of the trip he was traveling

at twice the speed, or 2s, for distance 48 - d, for 2 hours.

speed = distance/time

distance = speed * time

First part of trip:

48 - d = 2s * 2

d + 4s = 48 Equation 1

Second part of the trip:

d = s * 2

d = 2s =

Equation 2

Equations 1 and 2 form a system of equations in two unknowns, d and s.

d + 4s = 48

d = 2s

Substitute 2s for d in equation 1.

2s + 4s = 48

6s = 48 =

s=8

The speed in the second part is 8 mph.

The speed in the first part is 2s = 2(8) =

16.

The speed in the first part is 16 mph.

Check:

d = 2s = 2(8) = 16

48 - d = 48 - 16 = 32

The second part is 16 miles. The first part is 32 miles.

16 miles at 8 mph takes 2 hours.

32 miles at 16 mph takes 2 hours.

2 hours + 2 hours = 4 hours.

Our answer is correct.

Answer: The speed in the first part is 16 mph.

Answer:

x = -3

Step-by-step explanation:

System of equations has been given as,

y = 2x + 8

y = [tex]-\frac{2}{3}x[/tex]

Since, solution of the system of equations is the point of intersection on the graph.

Therefore, point of intersection or solution of the system will be,

(x, y) = (-3, 2)

This common point will satisfy both the equations.

And x = -3 will also both the equations.  

Answer:

x=11

Step-by-step explanation:

We would add 8 to both sides of the equation, leaving us with x=11

Answer: 31.18

Step-by-step explanation:

The problem is focused on mainly the right triangle made up of points M, Q, and R.  This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.  

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR.  Since MP is equal to 18, MR has to be 18 as well.  This means that the value of a is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18

Answer:

The fewest possible number of free throws Owen attempted is 15 throws

Step-by-step explanation:

From the first half,

72% = 72/100 = 18/25, reduced to its simplest ratio.

It means that he made at least 18 free throws in the first half of the season.

From the second half,

Let x be the fewest possible outcome of free throws, and the sum of total is 60% = 60/100 = 0.6

Considering the 6 free throws during the second half of the season,

(18+6)/(25+x) = 0.6

24/(25+x) = 0.6

Solving for x,

24 = 0.6(25+x)

24 = 15+0.6x

24-15 = 0.6x

9 = 0.6x

x = 9/0.6 = 15

x = 15 free throws

The fewest possible number of free throws Owen attempted is 15 throws
