Let x be the price of the breakfast.
We know that 20 percent of x is 1.80
Let's write this as a mathematical equation
0.2 x = 1.8
Let's divide both sides by 0.2 to isolate the x
x = 1.8 / 0.2
= 9
The price of the breakfast was $9.
Have an awesome day! :)
1.625 as a fraction is 1 5/8
15/8 simplified is 1 7/8
if you are using the word "and" to represent multiplication here you go:
first i would change both fractions to a mixed number
13/8×15/8=195/64
simplify
your answer would be 3 3/64
if you are using "and" to represent adding here you go:
1.625 as a fraction is 1 5/8
first i would change 1 5/8 to a mixed number: 13/8
so then add 15/8+13/8=28/8
simplify:
28÷4=7
8÷4=2
7/2=3 1/2
i hope this helped
Answer:
X^2+6X-7=0
Step-by-step explanation:
To identify the quadratic equation use the following method
(X-a)(X-b)=0
Where
a=-7
b=1
(X+7)(X-1)=0
X^2+7X-X-7=0
X^2+6X-7=0
Answer:
$478.80
Step-by-step explanation:
We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.
First of all, we will find cost of each meal with tax as:




Now, we will find total persons at the sport banquet as:


To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.


Therefore, the total cost of food for the banquet is $478.80.
Answer:
y = 2x - 6
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The y-intercept is already given and is -6.
By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).
Use the two points to find the slope using the following equation.

Plug the points into their respective positions and solve.

The slope is 2.
Your equation is y = 2x - 6.
