A sporting good store sells basketballs and footballs. Gavin pay $44 dollars for 3 basketballs and 2 footballs. Andrew pays $31

zzz [600]

Answer: The price of 1 football = $ 7 and price of 1 basket ball= $10

Step-by-step explanation:

Let x = price of 1 football.

y = price of 1 basketball.

As per given,

$3x+2y=44\ \ \ (i)$

$x+3y=31\ \ \ \ (ii)$

Multiply 3 to (ii) , we get

$3x+9y=93\ \ \ \ (iii)$

Eliminate (i) from (iii)

$7y=49\\\\\Rightarrow\ y=7$

Put this in (ii), we get

$x+3(7)=31\\\\\Rightarrow\ x+21=31\\\\\Rightarrow\ x=31-21=10\\\\\Rightarrow\ x=10$

Hence, the price of 1 football = $ 7 and price of 1 basket ball= $10

Graph the following set of parametric equations on your calculator and select the matching graph.

Anettt [7]

Answer:

Graph 2

Step-by-step explanation:

The equation x = t² - 3 is represented by exponential growth, ( t² ) so it's graph will be similar to the first graph, graph 1, in our options. Then again we have to consider the equation y = √t - 2, which will be similar to graph 4, but with a greater slope. This leaves us with a solution of graph b.

-3 2/7 times .14 as a decimal and a fraction

LenaWriter [7]

Answer:

-0.46 or -23/50

Step-by-step explanation:

We note that 0.14 is easily divisible by 7, so we can do this using the distributive property:

(-3 2/7)(0.14) = (-1)(3 + 2/7)(0.14)

= (-1)(3×0.14 +2/7×0.14)

= (-1)(0.42 +0.04)

= -0.46 . . . . . decimal form

= -46/100 . . . . place value

= -23/50 . . . . remove common factor of 2; fraction form

The product is -0.46 or -23/50.
