Answers
Fourteen is 28% of B) 50
Why, you ask? Let's see -
Let the unknown number be n, for 'number'.
Let's put the unknown n next to 28%
.28n% = 14
(Think, what times .28 equals 14? Look below to find out! ↓ )
Let's now do the opposite of the actual equation - divide the two known numbers by each other -
.28 ÷ 14 = 50
When in doubt, check your answer:
To check this, we would do the opposite - Multiplication
Multiply .28 by 50 to get 14 (At least you should get 14)
.28 × 50 DOES EQUAL 14! We were right! :D

B. The equation has a variable on both sides
C. The equation is true for any value of x.
Answers
Answer:
A
Step-by-step explanation:
If you simplify the equation you are left with 5 = -1, which is an untrue statement. Therefore, no matter what value you use for x you will always be left with 5 = -1.
Answer:
A
Step-by-step explanation:
The equation is not true for any value of x because it has 4x on both sides, but has both +5 and -1 on both sides, so this is impossible.
The equation would never work because the left side would always be bigger than the right side and vice versa.

Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2)
Let x be the number of miles.
Then, we have inequality:
Solve the inequality: .
Subtract 2 from both the sides:
Simplify:
Divide by 8 both sides we get;
as shown in figure 1.
4)
From the context of the problem :
we can say that Paul can travel 1 miles or less before reaching his limit of $10.
Answer:
A football team wants to by a football. The football costs $51. There are 11 members of the team. How much will each of the team members contribute to be able to purchase the football if they had $29 already.
Solution: Let the amount each team member contributes be x, then
11x + 29 ≥ 51
11x ≥ 51 - 29
11x ≥ 22
x ≥ 22/11
x ≥ 2
