Answer:

I am pretty sure $750

Step-by-step explanation:

Since there are 10 slices of cake, you would have to divded the cost ($2,500) by 10 to find out the cost per slice (you would get $250). Since we are finding the cost of 3 slices, you would mulitply 250 by 3, then you get your answer

The linear equation that has a slope of -7 and crosses the x-axis at (3, 0) is:

y =  -7x + 21

<h3>How to find the linear equation?</h3>

A general linear equation is:

y = a*x +b

Where a is the slope and b is the y-intercept.

The slope must be equal to the limit found in part a, and you say that it is equal to -7, so the slope is -7. And for how is written the problem, I understand that it crosses the x-axis at x = 3.

Then we will have:

y = -7*x + b

Such that, when x = 3, y = 0, then:

0 = -7*3 + b

21 = b

Then the linear equation is y = -7x + 21

Simplify the expression to one number using order of operations:
geniusboy [140]
<h2><u>COMBINED OPERATIONS</u></h2><h3>Exercise</h3>

First, let's solve the subtraction (in parentheses):

\mathsf{\dfrac{-8\left(2-6\right)}{2}}

\mathsf{\dfrac{-8(-4)}{2}}

Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:

\mathsf{\dfrac{-8(-4)}{2}}

\mathsf{\dfrac{32}{2}}

Finally, let's solve the division:

\mathsf{\dfrac{32}{2} = 16}

<h3><u>Answer</u>: 16</h3>

A toy airplane costs $4.84.. It costs 4 times as much as a toy car. What is the cost of the toy car? Show your work.
Elina [12.6K]
Cost of airplane toy = $4.84
let x be the cost of the toy car
cost of airplane toy is 4 times the cost of toy car; it means 
4x = $4.84
x = 4.84 / 4
x = 1.21
Thus, the cost of toy car is $1.21.
