Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.

Answers

Answer:

11

Step-by-step explanation:

so we just make a system of equations:

x+y=36

say that x is the larger and y is the smaller

x-3=2y

so we can combine the equations and solve for x and y

re-arrange x-3=2y to be x=2y+3

x+y=36

x=2y+3

insert the value for x into x into x+y=36

2y+3+y=36

3y+3=36

y=11

now insert that back into x+y=36

11+x=36

x=25

Out of the two numbers x and y, 11 is the smaller number

5/8- 3/8

Since the denominator is the same, we can subtract the numerators

(5-3) /8 = 2/8 = 1/4

The value of y is 225 when x is 50 from the given graph.

What is Coordinate System?

Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.

We need to find the value of y when x is fifty.

In the given graph we have to draw a perpendicular line at x =50.

Now we have to check the point where the perpendicular line touches the graph curve.

Take the corresponding value of y.

When x is 50 the value of y is nearly to 225.

Hence, the value of y is 225 when x is 50.

Convert 32% to the fraction [tex]\frac{32}{100}[/tex]

Since any percentage is out of 100, we make 100 the denominator.

[tex]\frac{32}{100}[/tex]  can be simplified because both 32 and 100 can be divided by 4 evenly.

32/4 = 8       100/4 = 25

Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.
The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??

Answers

Answer: See explanation

Step-by-step explanation:

Let the number of calls received the first evening be x.

The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9

The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27

Then, the expression for each evening can then b put together and solved further as:

x + (x - 9) + (3x - 27) = 94

x + x - 9 + 3x - 27 = 94

5x = 94 + 9 + 27.

5x = 130

x = 130/5

x = 26

First evening = 26 calls

Second evening = x - 9 = 26 - 9 = 17 calls

Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls

A basketball player has made 12 of his last 20 free throws, which is a free throw percentage of 60%.
How many more consecutive free throws would he need to make to raise his free throw percentage to 75%?

Answers

Answer:

Need ( 3 ) more consecutive free throws to make to raise his free throw percentage to 75%

A percentage is a way to describe a part of a whole. To raise his free throw percentage to 75% he needs to make 3 more baskets.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that A basketball player has made 12 of his last 20 free throws, which is equal to 60% of the free throw.

75% of the free throw will be equal to 15. Therefore, to raise his free throw percentage to 75% he needs to make 3 more baskets.
