See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.
Question #3:
17 = -13 - 8x
Add 13 to each side:
30 = -8x
Divide both sides by -8:
X = 30 / -8
X = -3 3/4
The union of the sets are the values that appear in both sets when plotted in a Venn diagram and if I'm not mistaking, I think the right answer is (B)
C. a-3x=0
Equations are like a balance scale. There needs to be an “=“
4d=56
d=14. Ad a result, Dorothy is 14 years old. Hope it help!
Answer:
16/45
Step-by-step explanation:
Step 1: When dividing fractions, use “KFC”. It means Keep the first fraction, Flip the second one, and
Change it to multiplication
-4/20 ÷ -9/16 → -4/20 ∙ 16/-9
Step 2: Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end. It’s easier arithmetic to reduce at this step. The first fraction reduces because both the numerator and denominator are divisible by 4.
-1/5 ∙ 16/-9
Step 3: Multiply numerators and denominators together to get one fraction
(-16)/(-45)
Step 4: Cancel out the negatives, a negative divided by a negative is a positive. Our final answer is
16/45
