2x = 8 so x = 8/2 = 4
or
3x = 12
x = 12/3
x = 4
answer: x = 4 (answer is your last choice)
Let's call x the price of a box of slime.
Gianna spent 4 × $58 for art supplies so 4(58) + 8x all together. We have
392 ≤ 4(58) + 8x ≤ 472
We can work with both inequalities at once. 4(58)=232 so we subtract that from all three sides.
160 ≤ 8x ≤ 240
Divide all three sides by 8, a positive number so the inequalities don't flip.
20 ≤ x ≤ 30
Answer: Least: $20, Most: $30
Answer:
7x² - 6x + 4
Step-by-step explanation:
(4x² - x + 6) - (-3x² + 5x + 2)
4x² - x + 6 + 3x² - 5x - 2
4x² + 3x² - x - 5x + 6 - 2
7x² - 6x + 4
Answer:
5 cups of soup mix
Step-by-step explanation:
3. You can make the addition easier by finding a common denominator 12.
7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 --> 21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12
To do this you need to multiply every numerator and denominator by the same number until the denominator is equal to 12. When it is 12 you can add up all the fractions to get 5.
I hope this helps!
