3y + 3 = 75
3y = 72
y = 24
y +1 = 25
y + 2 = 26

Answer:
enlargement: >1reduction: <11: same sizeStep-by-step explanation:
The scale factor of an enlargement is greater than 1.
The scale factor of a reduction is less than 1.
A scale factor of 1 will produce a congruent figure, one the same size as the original.
_____
A longer way to say it
A figure is enlarged when its dimensions are greater than those of the original. Then the ratio of dimensions will be ...
(greater than original)/(original) = greater than 1
Similarly, a figure is reduced when its dimensions are less than those of the original:
(less than original)/(original) = less than 1
Multiplying dimensions by a scale factor of 1 does not change them. The scaled figure is the same size as the original.

B.
Prepaid Single Phone Plan $45 for 16 GB
C.
Prepaid Family Plan 1 Person $30 for 1 GB
D.

The price per GB are;
Plan a = $30 ÷ 1 = $30 per GB
Plan b = $35 ÷ 6 = $5.8[tex]\overline 3[/tex] per GB and $40÷ 6 = $6.[tex]\overline 6[/tex] per GB for Family Plan
Plan c = 45 ÷ 16 = $2.8125 per GB and $3.125 per GB
Plan d = $65 for Unlimited Data = 65 ÷ ∞ ≈ 0; $70 for Unlimited Data = 0
Therefore, the plan with the cheapest price per GB from the given option is option B. Prepaid Single Phone Plan $45 for 16 GB.

Answer:
(a) Line 1
Step-by-step explanation:
The given point is only a solution to the equation for Line 1. This is shown in the attached graph.

Answer:
The second number is 90.
Step-by-step explanation:
The first statement isn't at all helpful when you start the problem. Three numbers add up to 185. Big deal. Hold that thought for later.
You need a place to start: think about some quantity to assign a variable name (letter) to. Look at the second statement.
The second number is 5 times the first. If x represents the first number, then 5 times that is 5x. So far, you have this:
x = first number
5x = second number
Next: The third number is 13 less than the second number. "13 less than" means to subtract 13 from something. But what? The second number.
5x - 13 = third number
Now the first statement is useful. All three numbers add up to 185.
x + 5x + (5x - 13) = 185
Combine like terms.
11x - 13 = 185
Add 13.
11x = 198
Divide by 11.
x = 18
Wait! Trick question. The problem asks for the second number, not the first.
5x = 5(18) = 90

One angle of a right triangle measures 36. 5 degrees. What is the measure of the other small angle?.
Answer:
The other small angle is 53.5 degrees
Step-by-step explanation:
We know that a right triangle has to have a 90 degree angle and 2 other small angles.
All triangles when adding up all of their "degrees" has tp equal 180 degrees.
Since we know that there is a 90 degree angle and a 36.5 degree angle.
All we have to do is add 90 plus 36.5, then subtract that sum onto 180.
90 + 36.5 = 126.5
180 - 126.5 = 53.5
So the answer is 53.5 degrees.
Hope this helps! :)

A right triangle is a triangle in which the angles sum up to 180 degrees. It is made up of three sides : the height, the base and the hypotenuse. One of the angles in a right triangle has a value of 90 degrees.
Missing angle = sum of angles in a triangle - (sum of the two given angles)
Missing angle = 180 - ( 90 + 36.5)
180 - 126.50
= 53.5 degrees

The sum of two polynomials is â€"yz2 â€" 3z2 â€" 4y 4. If one of the polynomials is y â€" 4yz2 â€" 3, what is the other polynomial? â€"2yz2 â€" 4y 7 â€"2yz2 â€" 3y 1 â€"5yz2 3z2 â€" 3y 1 3yz2 â€" 3z2 â€" 5y 7.
The sum of polynomials involves adding the polynomials
The other polynomial is [tex]y^3 -y^2+ 4y - 1[/tex]
The sum of the polynomials is given as:
[tex]Sum = y^3 + 3y^2 + 4y - 4[/tex]
One of the polynomials is given as:
[tex]P = 4y^2 - 3[/tex]
Represent the other polynomial with Q.
So, we have:
[tex]P +Q =Sum[/tex]
Substitute the expressions for P and Sum
[tex]4y^2 - 3 +Q =y^3 + 3y^2 + 4y - 4[/tex]
Make Q the subject
[tex]Q =y^3 + 3y^2 -4y^2+ 4y - 4 +3[/tex]
Evaluate like terms
[tex]Q =y^3 -y^2+ 4y - 1[/tex]
Hence, the other polynomial is [tex]y^3 -y^2+ 4y - 1[/tex]

in a class of 40 students, only 20% of the students are participating in an art competition. how many students are not taking part in the competition?
======================================================
Explanation:
There are two approaches.
Method 1)
20% of 40 = 0.20*40 = 8
Since 8 students are participating, this means 40-8 = 32 are not participating.
-----------
Method 2)
20% are participating, so 100% - 20% = 80% are not participating
80% of 40 = 0.80*40 = 32
