Pamela is 5 years younger than Jiri. The sum of their ages is 81. What is Jiri's age?

Answers

Answer 1
Jiri’s age is 43
Pamela is 5 years younger mean
Mean Jiri is old 5 years, take number of Jiri age minus Pamela age.
-> J-5=P
The sum mean plus
P+J=81
Use substitution for the equation 1 to find the answer.
(J-5) +J=81
2J-5=81
2J=86
J=43
Answer 2

Answer: Jiri is 43 years old

Step-by-step explanation:

Let x be the age of Pamela, and (x+5) be the age of Jri

Expression

x+(x+5)=81

Expand paranthesis

x+x+5=81

Combine like terms

2x+5=81

Subtract 5 on both sides

2x+5-5=81-5

2x=76

Divide 2 on both sides

2x/2=76/2

x=38

Since we've set Jiri's age as (x+5), we need to substitute the value of x

x+5=38+5=43

Hope this helps!! :)

Answers

Answer:

A. y = 2

B. x = 7/2

C. y = 12/5

D. x = 6

Step-by-step explanation:

A. Determination of y .

2x + 5y = 12

x = 1

2(1) + 5y = 12

2 + 5y = 12

Collect like terms

5y = 12 – 2

5y = 10

Divide both side by 5

y = 10 / 5

y = 2

B. Determination of x

2x + 5y = 12

y = 1

2x + 5(1) = 12

2x + 5 = 12

Collect like terms

2x = 12 – 5

2x = 7

Divide both side by 2

x = 7/2

C. Determination of y

2x + 5y = 12

x = 0

2(0) + 5y = 12

0 + 5y = 12

5y = 12

Divide both side by 5

y = 12/5

D. Determination of x

2x + 5y = 12

y = 0

2x + 5(0) = 12

2x + 0 = 12

2x = 12

Divide both side by 2

x = 12/2

Given the following number as an approximate measurement, 49.5 feet. What is the range of values for the actual value?

Answers

Answer:

range is 2

Step-by-step explanation:

The range of values for the actual value is 2.

A range is the simplest measurement of the difference between the values ​​in a dataset. To find the range, subtract the minimum value from the maximum value and ignore the other values. Where the minimum is 155 and the maximum is 720.

The statistical range for a particular dataset is the difference between the maximum and minimum values. For example, if the specified record is {2,5,8,10,3}, the range is 10 – 2 = 8. Therefore, the range can also be defined as the difference between the highest and lowest observations.

The triangle provided is an equilateral one, which means that the length of all sides is equal.

Let's start by taking two and finding x.

8x+1 = 3x+6 (Subtract 3x from both sides)

5x+1 = 6 (Subtract 1 from both sides)

5x = 5 (Divide 5 from both sides)

x = 1

Now we substitute x in all the equations to find the length.

8(1) + 1 = 9

3(1) + 6 = 9

4(1) + 5 = 9

Length = 9
