Answer:

7. 7.1+5.4+2.9=15.7

10.3+5.4=15.7

8. 373.4 - 152.9 = 220.5

373.4 - 153 = 220.4

220.4 - 0.1 = 220.5

9. 18.25 + 7.99 + 4.75 = 30.99

10. 1.05 + 3 + 4.28 + .95 = 9.28

11. 302.504

How do i find an equation for a line with an x-intercept of 4 and a y-intercept of -2
ivann1987 [24]

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Solve for g.<br> -3+5+6g=11-3g−3+5+6g=11−3g
PtichkaEL [24]

Answer: \mathrm{No\:Solution}

Step-by-step explanation:

\begin{bmatrix}-3+5+6g=1\\ 1-3g+5+6g=11-3g\end{bmatrix}

\begin{bmatrix}1-3\left(-\frac{1}{6}\right)+5+6\left(-\frac{1}{6}\right)=11-3\left(-\frac{1}{6}\right)\end{bmatrix}

\begin{bmatrix}\frac{11}{2}=\frac{23}{2}\end{bmatrix}

\frac{11}{2}=\frac{23}{2}\:\mathrm{\:is\:false,\:therefore\:the\:system\:of\:equations\:has\:no\:solution}

For a two day rental at the surf shop it costs $45 to rent a surf board and $60 to rent a paddle board. On a certain weekend the
Alla [95]

Answer:

19 paddle boards were rented.

Step-by-step explanation:

The rent of a surf board is $45

And the rent of a paddle board is $60

Total of paddle board and surf board rented were 44

let the paddle board rented be x

Hence, surf board rented will be 44-x

According to question we are given that 44 both  boards were rented means

45\cdot(44-x)+60\cdot x=2265

1980-45x+60x=2265

On solving the above equation we will get:

15x=285

x=19

\Rightarrow x=19

Hence, 19 the paddle boards were rented.
