The **value **of the **expression **at x = 8 and y = 2 will be 2.

The **result **of the computation that the **mathematical **model depicts is the expression's result when the necessary **parameters **and natural laws are given **quantities**.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the **PEMDAS **formula. To answer the problem **properly **and accurately, this **rule **is **applied**.

The **expression **is given as,

⇒ (2x - 12) + (1/2xy - 10)

The value of the **expression **at x = 8 and y = 2 will be **calculated **as,

⇒ (2 × 8 - 12) + (1/2 × 8 × 2 - 10)

⇒ (16 - 12) + (8 - 10)

⇒ 4 - 2

⇒ 2

The **value **of the **expression **at x = 8 and y = 2 will be 2.

More about the **value of the expression** link is given below.

**Step-by-step explanation:**

(2x-12)+(1/2xy-10)

- (2×8-12)+(1/2×8×2-10)
- (16-12)+(8-10)
- 4+(-2)
- 4-2
- 2

Question

The sume of of two numbers is 66. The larger number is two more than three times the smaller number. What are the two numbers?

Solution 1

X+y=66. Let's assume y is the larger number. Y=3x+2. Plug in Y. x+3X+2=66 4X=64. Therefore, x=16. We plug in X, Y=16(3) +2=50

Question

Write 560% as a decimal and as a mixed number

Solution 1

560% as a decimal = **5.6**

(move the decimal points 2 spaces to the left.)

560% as a mixed number =**5 3/5 **

(divide 560 by 100; 100 goes into 560 5 times so 5 will be your whole number and since you have 60 left you divide 60 by 100; 60/100 can be reduced to 3/5 if you divide the numerator and the denominator by 20)

hope this helps :)

(move the decimal points 2 spaces to the left.)

560% as a mixed number =

hope this helps :)

Question

A driver fills up his car's tank with 23 gallons of gas. After he drives 325 miles, he stops for fuel, and 12.5 gallons are needed to fill the tank. How many miles per gallon did he get?

Solution 1

23-12.5=10.5

325 divided by 10.5 gives you the mpg

the answer is 30.9 rounding out to about 31 miles per gallon.

325 divided by 10.5 gives you the mpg

the answer is 30.9 rounding out to about 31 miles per gallon.

Question

A construction crew has just finished building a road. the crew worked for 10 days. if they build 2 3/4 kilometers of road each day, what is the total length of road they built?

Solution 1

**Answer:**

The length made in 10 days is kilometers.

Total number of days the crew worked = 10

Length of road built each day = or kilometers

So, total length of road made in 10 days will be :

= 27.5 kilometers.

In fraction form we can write as :

kilometers.

Solution 2

2.75 x 10 = 27.5 or 27 1/2 kilometers total
