Answer:
24 = questions on test
Step-by-step explanation:
Questions answered correctly = questions on test * percent answered correctly
We know that she answered 18 correctly and that 75% were answered correctly
Substitute this information into the equation
18 = questions on test *.75
Divide by .75 on each side
18/.75 = questions on test *.75/.75
24 = questions on test
Howdy!
To do this we first have to find the unit rate of 2,600.
2,600/4=650 each week. Then, we just multiply 650x20, with 20 being the number of weeks.
650x20=13,000<---Answer
-Seth
3(4x - 2) = 2(6x - 3)
12x - 6 = 12x - 6
Add 6 on both sides
12x = 12x
Divide by 12 on both sides
x = x
That means this has infinite solutions. Your answer is B.
Answer:
x = 0
Step-by-step explanation:
You know the answer to this because you know the identity element for addition is 0: 5 + 0 = 5.
__
Or, you can make use of the addition property of equality and add -5 to both sides of the equation:
5 - 5 + x = 5 - 5
x = 0 . . . . . . . . . . simplify
