A county fair charges an entry fee of $7 and $0.75 for each ride token. You have $15. Write an expression that represents the amount (in dollars) you have left after entering the fair and purchasing n tokens (I need help figuring out these three questions):

Check the picture below.

the area of the region in white, is really the area of a trapezoid that has a height = 2, and bases of 3 and 6, so let's get its area

[tex]\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h=height\\ a,b=\stackrel{parallel~sides}{bases}\\[-0.5em] \hrulefill\\ h=2\\ a=3\\ b=6 \end{cases}\implies A=\cfrac{2(3+6)}{2}\implies A=9[/tex]

now that we know the area in white, let's check all expressions, and whichever does NOT result in 9, is it.

[tex]\boxed{A}\qquad (2)(6)-\cfrac{1}{2}(2)(3)\implies 12-3\implies 9 \\\\\\ \boxed{B}\qquad (4)(6)-\cfrac{1}{2}(4)(3)-2(3)-\cfrac{1}{2}(3)(2)\implies 24-6-6-3\implies 9 \\\\\\ \boxed{C}\qquad (3)(2)+\cfrac{1}{2}(3)(2)\implies 6+3\implies 9 \\\\\\ \boxed{D}\qquad (6)(2)+\cfrac{1}{2}(3)(4)\implies 12+6\implies 18\qquad \textit{\Large \checkmark}[/tex]

For problem 1:

When dividing with decimals, you move the decimal to the right until the number is whole.

EX:

20.8 ÷ 2.6 → 208 ÷ 26

Then you divide like normal.

Step-by-step explanation:

Answer:

Solution: (-1, -1)

Step-by-step explanation:

y=4x+2

y=-4/3x-2

Solve by graphing.

First, you need to plot the y-intercept.

y=4x+2

2 will be your y-intercept.

Next, you plot your slope.

y=4x+2

From your y-intercept, you will go up 4 and right one space, if you run out of space go down 4 and left 1.

Now repeat the same steps for the next one.

y=-4/3x-2

Plot your y-intercept.

y=-4/3x-2

because your slope is negative you will go down 4 and right 3, if you run out of room go up 4 and left 3.

Then draw connecting lines and wherever the lines intersect, that's going to be your solution. In this case, the solution is (-1, -1).

Hope this helps :)

Answer:

x = 14

Step-by-step explanation:

3x/-8 = -21/4

(3x/-8)×-8 =( -21/4)×-8

3x = 42

3x/3 = 42/3

x = 14

hope it's helpful

Answer:

x = 14

Step-by-step explanation:

to solve this you have to first move 3/-8 to the other side and divide while keeping x on the same side.

now to divide you must flip over 3/8 and multiply so 21/4 x 8/3 ( negative sign cross off because there are two of them) so 3 and 21 cross off leaving 7 in the numerator 4 and 8 cross of leaving 2 in the numerator and then 7 and 2 get multiplied and you will get 14.

Answer:

X = 3

Step-by-step explanation:

-(-5) is also the same as + 5, so the equation would be 8x + 5 = 29

Subtract 5 from both side of the equation

8x+5-5 = 29 -5

8x = 24

Then divide both sides by 8

Final answer x=3

Step-by-step explanation:

Answer:

1,3,5 are congruent.

Step-by-step explanation:

The order from least to greatest of the given number set is 6.478, 6.5, 6.503, 6.6.

1) Given that, 843×61 and 478×38.

Here, 843×61 = 51423 and 478×38=18164

2) The given table with x+1 and y+3.

Here, put x= 1, 2, 3, 4,....in x+1, we get 2, 3, 4, 5,....

Put y=1, 2, 3, 4,...... in y+3, we get 4, 5, 6, 7,......

3) Given that, 4/9 ×3

= 4/3

4) The given numbers are 6.5, 6.503, 6.6, 6.478

Now, the order from least to greatest is 6.478, 6.5, 6.503, 6.6

5) 3.98+0.432=4.412

2.6-0.75= 1.85
