Amelia had some moneynsaved before she started saving $2 each week.After 3 weeks, her total savings were $16. how much money had amelia saved at the begining of 3 weeks?

Answer:

x = 1/2

Step-by-step explanation:

6x-3= 0       (add 3 to both sides)

    +3   +3

6x=3            (divide by 6 to isolate x)

/6   /6

3/6= 1/2       (simplify)

x=1/2

Answer:

2

Step-by-step explanation:

4x + 2 =4 => 4x = 2 => x = 0,5

if x =0,5 => 2x + 1 = 0,5.2 + 1 = 2

The values of "2x+1" will be "2".

The expression,

→ [tex]4x+2=4[/tex]

By subtracting "2" from both sides, we get

→ [tex]4x+2-2=4-2[/tex]

→             [tex]4x=2[/tex]

→               [tex]x = \frac{2}{4}[/tex]

→               [tex]x = 0.5[/tex]

By putting the value of "x" in the expression "2x+1", we get

→ [tex]2x+1 = 2(0.5)+1[/tex]

→            [tex]= 1+1[/tex]

→            [tex]= 2[/tex]    

Thus the above answer is right.

That equation is y = mx + b, where m is the slope and b is the y-intercept.  You must have the values of both of these to write the equation of a straight line in slope-intercept form.

Answer: y=2x-8

Step-by-step explanation:

Use the slope formula y2-y1/x2-x1. Plug the points in. You get 2 which is the m/slope. Then you plug that into y=Mx+b and then find the y isn’t with y=Mx+b and you get -8. Plug it all in and you get y= 2x-8

$12.00

Step-by-step explanation:

The cost of each ticket will be $18.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change.

Then the cost of the ticket will be

Cost = ($50 - $23) / 2

Cost = $27

If Tristan used a coupon for 25% off. Then the original price for all tickets will be

Original cost = $27 / 0.75

Original cost = $36

Then the cost of each ticket will be

Cost of each ticket = $36 / 2

Cost of each ticket = $18

Step-by-step explanation:

"A rectangular room measures 3.8 meters in length and 4.9 meters in width. Jana multiplies both numbers together. Which expression would be best for her to use to check the reasonableness of her decimal multiplication?"

given that

the length is 3.8m long and,

width is 4.9m wide

The expression for the area is

Area= length * width

Area= 3.8*4.9

Area= 18.62 m^2

Therefore the expression best for her to use to check the reasonableness of her decimal multiplication is the area which is  18.62 m^2

(145/7) / (5/7) =

145/7 * 7/5 =

145/5 =

29 miles per gallon

Answer:

Following are the solution to this question:

Step-by-step explanation:

For incentive A

The car value = 57000

Calculating debt[tex]= 57000 - 10000[/tex]

                            [tex]= 47000[/tex]

Calculating the debt value after incentive [tex]= 47000 - 5000[/tex]

                                                                    [tex]= 42000[/tex]

[tex]PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}[/tex]

         [tex]= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}[/tex]

         [tex]= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89[/tex]

For incentive  B

The car value = 57000

Calculating the debt value [tex]= 57000 - 10000[/tex]

                                            [tex]= 47000[/tex]

Calculating the monthly payment =[tex]\frac{47000}{(12*4)}[/tex]

                                                        [tex]= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166[/tex]

difference:

[tex]=121.89 - 979.166\\\\ = - 854.276[/tex]

Step-by-step explanation:

44/(4+7) = 4

4 * 7 =28

Step-by-step explanation:

Ok, so in a standard equation, there can’t be any fractions, so you would have to multiply everything by 3, making the equation 3y+3=2(x-8) (p.s. don’t multiply the parentheses, leave the numbers in them alone for now). Then, you would go through with the equation process: 3y+3=2x-16. You move the 3 over to the right to make 3y=2x-19. Move the x to the left, -2x+3y=-19. But, there is a problem. The first term of this equation can’t be negative(yes, in standard form, x has to come first). So, you have to multiply everything by -1, resulting in the answer 2x-3y=19. I hope this helps!(The format for a standard form equation is: Ax+By=C).

Substitute values into point-slope form

[tex]y-y_1=m(x-x_1)\\\\y -(-1)=-\frac{3}{2} (x -8)\\\\y+1 = -\frac{3}{2}x+12\\\\y = -\frac{3}{2}x +12-1\\\\y =-\frac{3}{2}x +11[/tex]

The equation of line passes through the point (8, -1) will be;

⇒ y = - 3/2x + 11

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (8, - 1).

And, The slope of the line is,

⇒ m = - 3/2

Now,

Since, The equation of line passes through the point (8, -1).

And, Slope of the line is,

⇒ m = - 3/2

Thus, The equation of line with slope - 3/2 is,

⇒ y - (-1) = - 3/2 (x - 8)

⇒ y + 1 = - 3/2 (x - 8)

⇒ y + 1 = - 3/2x + 12

⇒ y = - 3/2x + 12 - 1

⇒ y = - 3/2x + 11

Therefore, The equation of line passes through the point (8, -1) with slope - 3/2 is,

⇒ y = - 3/2x + 11
