Answer:
The answer to all of those questions would be x=-1.8
Step-by-step explanation:
7x(x + 1.8) = 0 - Distribute through the Parenthesis -
7x^2 + 12.6x = 0
x(7x + 12.6) = 0
x = 0
7x + 12.6 = 0
7x = -12.6
x = -12.6/7
x = -1.8
so x = 0 or x = -1.8
Step-by-step explanation:
The answer would be:
5(-4) - 8
-20 - 8
-28
notice, that, pure juice is 100% juice, dohhh, thus 100/100 = 1.00
50% is 50/100 or 0.50 in decimal format
so..... whatever those two quantities amount to, that is, the 50% and pure juice, or (4)(0.50) + (x)(1.00)
they will equal the mixture desired 60% juice, or 0.60, namely (4+x)(0.60)
thus (4)(0.50) + (x)(1.00) = (4+x)(0.60)
solve for "x"
Hello!
Here's how much each person stacked:
Ronnie -- 0.25 of the 40 pizzas.
Mack -- 9/40
Kim -- 35% of the 40 pizzas.
Ada -- rest of the pizzas.
Now, the questions asks for who stacked the most pizzas.
First, find our how many pizzas they stacked out of 40.
40 × 0.25 = 10
40 × 35% = 14
10 + 9 + 14 = 33
40 - 33 = 7
This means that Ronnie stacked 10 pizzas, Mack stacked 9 pizzas, Kim stacked 14 pizzas, and Ada stacked 7 pizzas.
ANSWER:
Kim stacked the most pizzas since she stacked 14 of them.
