5x+4-129=0
5x=125
x=25
A=3x-13=75-13=62
C = 64
then we know all the angles in a triangle add up to 180 also
so we can do 64 + (2x + 4) + (3x - 13) = 180
combine like terms:
55 + 5x = 180
solve: x = 25
plug this back into the equation for angle A:
2(25) + 4
A = 54

Answer:
C 18(2 + 3)
Step-by-step explanation:
The GCD of 36 and 54 is their difference, 18. Factoring that out of the sum, you have ...
36 + 54 = (18·2 + 18·3) = 18(2 + 3) . . . . matches choice C
A triangle has one side that measures 5 units and another side that
measures 7 units. What are two possible lengths for the third side?
Explain why you chose the lengths you did.
Answers
Answer:
see explanation
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is between the limits
difference of 2 sides < x < sum of 2 sides, that is
7 - 5 < x < 7 + 5 , then
2 < x < 12
Choose any 2 values between 2 and 12 as third side, so
third side could be 6 or 9 for example

Sugar and flour are mixed in the ratio 3.5 in a sweet recipe in another recipe 15 parts of flour are used if these two ingredeints on both recipes are in both recipes are an equivalent ratio
Answers
Answer: 9
Step-by-step explanation:
Here is the completed question.
Sugar and flour are mixed in the ratio 3:5 in a sweet recipe. In another recipe, 15 parts of flour are used. If these two ingredients in both recipes are in an equivalent ratio, how many parts of sugar should be used?
Ratio of sugar and flour = 3:5
Since 15 parts of flour are used, the parts of sugar that should be used will be:
= 15 ÷ 5/3
= 15 × 3/5
= 3 × 3
= 9

A) I only
B) II only
C) III only
D) I and II only
Answers
Answer:
The final answer is D) I and II only
Step-by-step explanation:
Think bout what the formula is
y=mx+b
in this case
the slope of the graph is
5/ 9 , which means that for an increase of 1.
C= 5 /9 (F)
C=
5 /9 (1)= 5 /9
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of
9 /5 degrees Fahrenheit.
Statement II is also true since only answer that has both statement I and statement II as true is D, is not true since 25/81 not 1 degree.

The capacity of a small children’s swimming pool is 106 gallons of water. There are currently 15 gallons of water in the pool. You are filling the pool at a rate of 2 gallons per minute.
1. Write an equation that gives the amount y (in gallons) of water in the pool as a function of the number x minutes from now.
2. After how many minutes will the pool be full?
Answers
Answer:
1. y=2x+15
2. 45.5 min
Step-by-step explanation:
1. You find 2x by looking at the give rate of gallons (2) a min (x). This information is given in the word problem. This gives the equation of y=2x. But you already have 15 gallons in the pool, so you need to add the +15 at the end of the equation giving you y=2x+15.
2. Y is the total gallons. This is 106 gallons (given in the word problem). We are trying to solve for x (# of minutes to fill the pool). 106=2x+15. subtract 15 from both sides giving 91=2x. Divide both sides by 2 giving x=45.5. It will take 45.5 minutes to fill up the pool.
