Answer:
A.
Step-by-step explanation:
using FIOL (first, inner, outer, last) to factor
Answer:
a. No
b. 2.25 days
Step-by-step explanation:
0.75x + 3 = 0.25x + 5.25
a......................
Constants are $3 and $5.25 respectively
Topping costs $0.75 and $0.25 respectively
To have same cost the toppings number would be different as cost is different.
Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:
The answer is NO due to two different variables in the equation
b.......................
Constants are $3 and $5.25 respectively
Joseph adds $0.75 each day and Kelsey spends $0.25 each day
Number of days should be same in this case, so variable will be same and the result (amount left in bank) is same.
<u>So the equation for this case is:</u>
<u>Solving, we get:</u>
- 0.75x + 0.25x = 5.25 - 3
- x = 2.25
This is the solution to equation despite being a whole number.
Answer:
20%
Step-by-step explanation:
70/350 = 0.2
0.2 x 100 = 20%
Answer:
x=4
y=3
Step-by-step explanation:
Answer:
Step-by-step explanation:
For example, we'll use this quadratic equation.
To understand how to plug it into the formula we need to know what each term represents.
So the equation above would be put into the formula like this.
Then we would solve
Now, the equation will branch off into one that solves when addition and one when subtraction.
So x={-3, -2} (-3 and -2)
