The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
2x + 3y = 8 ...1
3x + 5y = 13 ...2
Multiply equation 1 by 3 and equation 2 by -2, then we have
6x + 9y = 24
-6x - 10y = - 26
Add the above equations, then we have
- 26 + 24 = 9y - 10y
y = 2
Then the value of the variable 'x' is calculated as,
3x + 5(2) = 13
3x + 10 = 13
3x = 3
x = 1
Then the value of the expression x + y is calculated as,
⇒ x + y
⇒ 1 + 2
⇒ 3
The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

Stefan sells Jin a bicycle for $127 and a helmet for $17.The total cost for Jin is 120% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally?How much money did he make by selling the bicycle and helmet to Jin?
Answer:
Stefan spent $120 originally
He made $24 dollars by selling the bicycle and helmet to Jin
Step-by-step explanation:
First, find the total cost:
127 + 17
= 144
To find the original cost, divide this by 1.2
144/1.2
= 120
So, Stefan spent $120 originally.
Now, find how much he made by subtracting 120 from 144:
144 - 120
= 24
So, he made $24 dollars by selling the bicycle and helmet to Jin.

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.
ABC is similar to triangle CED and is dilated by a factor of 3 so the base is 36.
using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE

Three tanks are capable of holding 361,841, and 901 of the greatest vessel winch can be used to fill each one of them on exact number of time
Answer:
Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
Step-by-step explanation:
Three tanks are capable of holding [tex]361,841,901[/tex]
To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]
[tex]361=19^2\\841=29^2\\901=17(53)[/tex]
Therefore,
[tex]HCF(361,841,901)=1[/tex]
So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
11) Peyton is sitting on the ground at the park flying a kite. The length of the kite string is 50 feet and the kite is directly above a tree. Peyton is sitting 25 feet away from the tree. How high is the kite flying in the air? Round to the nearest tenth.
Answer: 43.30 ft
Step-by-step explanation:
Given
The length of the string is [tex]L=50\ ft[/tex]
Distance between Peyton and the tree is [tex]x=25\ ft[/tex]
Using the figure, apply Pythagoras theorem
[tex]\Rightarrow L^2=h^2+x^2\\\Rightarrow h^2=50^2-25^2\\\Rightarrow h=\sqrt{2500-625}=43.30\ ft[/tex]
The kite is flying 43.30 ft above the ground

eve plays basketball. she makes 4 free throws for every 3 free throws that she misses. if she missed 24 free throws at her last practice, how many free throws did she make?
Answer:
She made 32 free throw shots.
Step-by-step explanation:
Based on the given information, one can form the general equation;
[tex]\frac{made}{missed}[/tex]
Substitute in the given values;
[tex]\frac{4}{3}[/tex]
Assuming that the rates at which this proportion exists is constant, and one knows the number she missed, but not the number she made then one can say;
[tex]\frac{made}{missed}= \frac{4}{3} = \frac{made}{24}[/tex]
Solve the proportion using cross products;
[tex]\frac{4}{3}=\frac{made}{24}\\\\\\(4)(24)=(3)(made)\\\\96=3made[/tex]
Inverse operations,
[tex]96=3made\\/3\\\\32=made[/tex]
Answer:
32 free throws

Answer For The Number 22: Factors of 22 are 1, 2, 11, 22. There are 4 integers that are factors of 22. The greatest factor of 22 is 22. 3.
Answer For The Problem 2x3 (Divide it by the numbers I give you meaning divide the number two by what I give yo and the other number 3 by it.
The common factors for 2,3 are −1,1 . The numbers do not contain any common variable factors. The GCF (HCF) of the numerical factors −1,1 is 1 .The number is one.
Answer For The Problem 2x5 is also 1 so decide both 2&5 by 1 then multiply. After doing that for answers 2&3 add them. last if you then subtract 22 that might be the answer so put that & also put the answer of the greatest common factor of 22 which is 3. Make sure to include that the one where you subtracted 3 was the greatest common factor for 22.
Ben is rock climbing in the Grand Canyon. He starts off 59.3 feet above sea level and descends into the canyon. The difference between his starting and ending elevation is 129.6 feet. What is Ben's final elevation?
Answer: -70.3 feet
Step-by-step explanation:
Let Ben's final elevation be represented by x.
We are informed that he starts off 59.3feet above sea level and descends into the canyon and that the difference between his starting and ending elevation is 129.6 feet. This will then be expressed in an equation as:
59.3 - x = 129.6
x = 59.3 - 129.6
x = -70.3
Therefore, the final elevation is -70.3 feet.

Paula has $50 in a savings account that earns 5% interest per year. The interest is not compounded .How much will she have in 1 year?
Answer: $52.50
Step-by-step explanation:
There is $50 in the account and it earns interest at a rate of 5% a year.
This interest is not compounded therefore it is simple interest.
To calculate amount earned with simple interest is:
= Deposit * ( 1 + rate * time)
= 50 * ( 1 + 5% * 1 year)
= $52.50
