65 total test items were on the test.
Answer:
84 juice bottles
Step-by-step explanation:
Given the ratio of grapefruit juice, pineapple juice, and tomato juice bottles as
3:1:2
Let the total number of bottles available be R
If there are 14 pineapple juice bottles, then
1/(3 + 1 + 2) * R = 14
1/6 * R = 14
multiply both sides by 6
R = 14 * 6
= 84
This means there are 84 bottles in all
I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped).
Hope I helped! ;)
Answer:
B, 7/20
Step-by-step explanation:
If two events are mutually exclusive that means that there is no intersection
so in the union formula: AUB=A+B-A∩B
A∩B=0
we can write P(a)=x
7/10=7/20+x+0
7/10-7/20=x
x=7/20
Answer:

Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 6 from both sides:
2x + 6 (-6) = -r - 15 (-6)
2x = -r + (-15 - 6)
2x = -r + (-21)
2x = - r - 21
Next, divide 2 from both sides:
