Which expression is equivalent to 30(1/2x-2)+40(3/4y-4)?1.45xy-220
2.15x-30y-220
3.15x+30y-220
4.15x+30y-64
Answers
The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.
What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 30(1/2x - 2) + 40(3/4y - 4)
Simplify the expression, then we have
⇒ 30(1/2x - 2) + 40(3/4y - 4)
⇒ 15x - 60 + 30y - 160
⇒ 15x + 30y - 220
The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.

For this case, we want to know what percentage of 75 represents the amount of "10". For this, we make a rule of three:
75 ---------------> 100%
10 ---------------> x
Where the variable "x" establishes the percentage that represents 10 having a base of 75.
Thus, 10 represents, approximately 13.3% of 75.
Answer:
The most appropriate option is option B. For the percentage, multiply by 100.
⇒ 13.33 percent of 75 is 10
Here we have to find the percentage
of 75 percent to get 10
Let us assume the percent is = x
Therefore,
To find the x percent of 75
Divide x by 100 and multiply it with 75
Then,
⇒ 75x/100
Now equate it to 10
Therefore,
⇒ 75x/100 = 10
⇒ 75x = 1000
⇒ x = 1000/75
⇒ x = 13.33%
Hence the percentage is,
⇒ x = 13.33%

The required it will take 10 years to earn $500 in interest. Option C is correct.
What is simple interest?
Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
SI= Principal×rate×time]
Here,
The formula for simple interest is:
I = Prt
We know that the principal (P) is $2,000, the interest rate (r) is 2.5% or 0.025 as a decimal, and we want to find the time (t) it takes to earn $500 in interest.
Substituting these values into the formula, we get:
$500 = 2,000 * 0.025 * t
$500 = 50t
t = 500 / 50 = 10 years
Therefore, it will take 10 years to earn $500 in interest.
