PLS HELP ITS A MAJOR GRADE AND DUE TOMORROW

Mathematics
1 answer:
Alexus [3.1K]3 years ago
7 0

Answer:

*See below*

Step-by-step explanation:

<u>Identify and Explain Error</u>

The method shown is using fractions to compare costs. This strategy does not work due to the fact that they have not factored in the $55 he pays for the car before hand. Also, 150 divided by 0.5 does not equal 30, it equals 300 so, even if he did not pay $55 beforehand, the equation is still incorrect.

<u>Correct Work/Solution</u>

$55 to rent

$0.50 per mile

Let's start by removing $55 from $150 to see how many dollars is left over for gas.

150 - 55 = 95

Then, divide 95 by 0.5

95 ÷ 0.5 = 190

He can drive at least 190 miles.

<u>Share Strategy</u>

Since he starts off paying $55 dollars out of $150, we need to subtract $55 by $150 to see how much cash he has left over for mileage. $150 minus $55 equals $95 so, he has $95 left over for mileage. $95 will then be divided by $0.50 to find out how many miles he can drive. We are dividing by $0.50 because that's the cost per mile. $95 divided by $0.50 equals 190 so he can drive at least 190 miles.

Note:

Hope this helps :)

Have a great day!

Which point-slope equation represents a line that passes through (3, –2) with a slope of -4/5?
alexira [117]

Answer:

y+2=-\frac{4}{5}(x-3)

C is correct equation.

Step-by-step explanation:

We are given a point and slope of a line. Using point slope form formula to find the equation of line and match the correct option.

Formula:

y-y_1=m(x-x_1)

where,

slope (m)=-\frac{4}{5}

Point:(x_1,y_1)\rightarrow (3,-2)

Equation of line:

y-(-2)=-\frac{4}{5}(x-3)

y+2=-\frac{4}{5}(x-3)

Thus, C is correct equation of given information.

Lin sold 4 more shirts than Greg. Fran sold 3 times as many shirts as Lin. In total the three sold 51 shirts. Which represents t
Alex17521 [72]
 <span>Your Answer: D 

Why.... 

You can make equations out of the information 
Let L be Lin, G be Greg, and F be Fran 

L = 4 + G ---"Lin sold 4 more shirts than Greg" 
F = 3L ---"Fran sold 3 times as many shirts as Lin" 
F + G + L = 51 ---"In total the three sold 51 shirts" 

Use F + G + L = 51 
Substitute the equations in for F and L (because you need to know the G) like this.... 

(3L) + G + (4+G) = 51 

You still have a variable besides G in there... you can use the L= 4+G and substitute again so that there are only G's 

( 3(4+G) ) + G + (4+G) = 51 ---- SIMPLIFY :D 
( 12 + 3G ) + G + 4 + G = 51 
12 + 3G + G + 4 + G = 51 ---Combine like terms 
16 + 5G = 51 </span>

Solve 2x^2 − 8x = −7
kenny6666 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

                                2x²  -   8x   =  - 7

Divide by 2

\frac{2}{2} x^{2}  - \frac{8}{2} x    = \frac{-7}{2}

Complete the trinomial

x^{2}  - 4x + (2)^{2}  = \frac{-7}{2} + (2)^{2}

Simplify

x^{2}  - 4x  + (2)^{2}  = \frac{- 7 + 4}{2}

x^{2}  - 4x + 4 = \frac{-3}{2}

Factor

(x - 2)²  =  \frac{-3}{2}

Get the square root

\sqrt{(x - 2)^{2}} = \sqrt{\frac{-3}{2}}

Simplification

               x - 2 =± \sqrt{\frac{3}{2}} i

      x₁ = 2 + \sqrt{\frac{3}{2}} i

       x₂ = 2 - \sqrt{\frac{3}{2}}
