Maria's kite tail was 3 1/2 feet long. Max's kite tail was 2 1/4 feet long. How much shorts was max's kite tail in inches?

8090 [49]

Answer: $\frac{5}{4}\ ft$

Step-by-step explanation:

Given

Maria kite tail is $3\ \frac{1}{2}\ ft$ long

Max's kite tail is $2\ \frac{1}{4}\ ft$ long

Converting it to a fraction

Maria kite tail

$\Rightarrow \dfrac{3\times2+1}{2}=\dfrac{7}{2}\ ft$

Max's kite tail

$\Rightarrow \dfrac{2\times4+1}{4}=\dfrac{9}{4}\ ft$

Difference between lengths

$\Rightarrow \dfrac{7}{2}-\dfrac{9}{4}\\\Rightarrow \dfrac{14-9}{4}=\dfrac{5}{4}\ ft$

Max's tail is $\frac{5}{4}\ ft$ short than Maria kite tail

Write an equation that represents the function. (linear equations)

irinina [24]

Answer:

y = 2x + 2

Step-by-step explanation:

First solve for the slope using $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$\frac{8-2}{3-0}$ = 2

Plug the slope into the slope intercept form equation y = mx + b

y = 2x + b

To solve for b, plug in any (x, y) point on the table.

2 = 2(0) + b

2 = b

Now you can plug the b value into your equation.

y = 2x + 2

Violet knows that her subscription rate for the basic tier of cable television increased from $18.20 to $19.50 at some point dur

mezya [45]

The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
