PLEASE HELP. Susan needs to buy plastic forks. Brand A has a box of 25 forks for $2.12. Brand B has a box of 72 forks for $5.09.

torisob [31]

To find the price per unit, divide the total price by the number of units.

2.12/25=0.08

5.09/72=0.07

Brand B is the better buy. It is cheaper per unit.

Against the wind a commercial airline in South America flew 630 miles in 3.5 hours. With a tailwind the return trip took 3 hours

Salsk061 [2.6K]

Answer:

The speed of plane is $195\ mph$ , and speed wind is $15\ mph$ .

Step-by-step explanation:

Given against the wind the airline flew $630$ miles in $3.5$ hours.

including the tailwind the return trip took $3$ hours.

Let speed of plane is $x$ .

Also, speed of the wind is $y$ .

Now, we will find speed on each case.

Speed against the wind is $\frac{630}{3.5}=180\ mph$

Speed with the wind is $\frac{630}{3}=210\ mph$

Now, we will write the equation

$x+y=210\\x-y=180$

Add these equation we get,

$2x=390\\x=\frac{390}{2}\\x=195\ mph$

Now, plug this value in $x+y=210$ to get speed of wind

$195+y=210\\y=210-195\\y=15\ mph$

So, the speed of plane in still air is $195\ mph$ , and speed of the wind is $15\ mph$ .

the answer is D

Step-by-step explanation:

the equation works with every number placed where the x is, for example:

4(5+1)= 4×5 + 4

4×6=20+4

24=24

but it also works with

4(11+1)= 4×11 + 4

4×12=44+4

48=48
