bearing in mind that an explicit form is simply the sequence written as a function of some variables, so we simply simplify and add like-terms.

1 yard = 3 feet:
21 feet / 3 ft = 7 yards
12 feet / 3 feet = 4 yards
7 x 4 = 28 square yards
he will need 28 tiles
Answer:
98.88
Step-by-step explanation:
I used a calculator and that's what it said the answer is srry if it might be wrong-
x=3 and y=−2
Step-by-step explanation:
Solve8x+5y=14for x:
8x+5y=14
8x+5y+−5y=14+−5y(Add -5y to both sides)
8x=−5y+14
8x8=−5y+148(Divide both sides by 8)
x=−58y+74
Step: Substitute−58y+74forxin−4x−5y=−2:
−4x−5y=−2
−4(−58y+74)−5y=−2
−52y−7=−2(Simplify both sides of the equation)
−52y−7+7=−2+7(Add 7 to both sides)
−52y=5
−52y−52=5−52(Divide both sides by (-5)/2)
y=−2
Step: Substitute−2foryinx=−58y+74:
x=−58y+74
x=−58(−2)+74
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=−2
The point total possible for the given course is equal to 500.
What is a Percent?
- A ratio whose second term is 100 is known as a percent.
- Parts per hundred are used in percentages.
- The mathematical representation of percent is %.
- The percent formula is given as,
, where b is the base number, x is the number being compared to b, and p is the percent in decimal form.
In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.
So, the total number of points you require for a B is calculated as,

So, the value of x is 400.
It is given that you need 80% of the course total for a B.

Here, we have to find the base number (b).
We have, x = 80% of b

Simplifying, we get

Therefore, 500 points were possible in the course.
