3x-10=2x+5

x=15

m∠3=2(15)+5

      =35

m∠1=m∠3 (vert. opp. ∠)

       = 35

Simon wants to find out which shop has the best frozen fruit drink in town. How could Simon conduct a survey with a sample that is representative of the population

Answers

Answer:

Step-by-step explanation:

The best way to do this would be to choose a random number of individuals that have bought a frozen fruit drink to survey. Then this same number of individuals should be surveyed in every single shop in the town. This would allow you to gather data from all of the shops and make sure that the sample is completely representative of the population as long as the individuals are chosen completely at random without introducing any external bias to the choice.

Solve the system of equations.

y = x + 3
[tex]y=x^{2} +7x+8[/tex]

A.
(-1,-4) and (-5,-8)
B.
(-1,2) and (-5,-2)
C.
(1,4) and (5,8)
D.
(-1,-2) and (-5,2)

Answers

Answer:

B.  (-1,2) and (-5,-2)

Step-by-step explanation:

Substitute x + 3 in for y in the second equation.  you get

[tex]x + 3 = x^{2} + 7x + 8\\x^{2} + 6x + 5 = 0[/tex]

(x + 1)(x + 5) = 0

x + 1 = 0    or  x + 5 = 0

x = - 1       or     x = -5

Using the first equation, let x = -1  and x = -5 in order to get the corresponding values for y

y = -1 + 3 = 2           and y = -5 + 3 = -2

So, B is the correct answer.

The amount spent on movies

40-12.5

$27.5

A movie ticket costs $5.

We need to find how many times can she go to the movies.

To find this we need to divide $27.5 by 5

$27.5/5=5.5

Robin can go 6 times to the movies.

A circular race track is 62.8 miles around. A driver is moving at 5 miles an hour driving from the outside to the center of the track. How long will it take for him to arrive?
Calculate the time it takes to travel to the center.

Answers

G I V E N

Speed of driver = 5 miles/hours

Distance to be covered = 62.8 miles

F O R M U L A  ~  U S E D

Speed = Distance/Time

S O L U T I O N

Time = Distance/Speed

= 62.8 miles / 5 miles / hour

= 12.56 hours

It will take 12.56 hours to cover 62.8 miles, if the driver is moving

with 5 miles/hours

Write a linear equation that gives the rule for this table.
Hint: Linear Functions are of the form y=mx+b

Answers

Answer:

y=x

Step-by-step explanation:

If we look at this then this is a y=mx+b graph

first lets find the rise/run

so rise = how much it goes up and run = how much it goes right or left

the rise/run of this graph is 1 because each time it goes one up it goes one right.

B= y intercept and the y intercept is 0

So it is y=1x+0 or y=x

answer = y=x

Find the unknown angle​

Answers

Answer:

77 degrees

Step-by-step explanation:

Right triangles always add up to 180 degrees. We know that one angle is 23 degrees, angle A is missing, and the last angle is a right angle which is equal to 90 degrees. Knowing what we know, we must subtract the two known angles from 180 to get angle A.

180 - 90 = 90

90 - 23 = 77

Angle A is equal to 77 degrees.
