Rosa bought 1 pound of cashews and 2 pounds of peanuts for $10. At the same store, Sabrina bought 2 pounds of cashews and 1 poun
Valentin [98]

Answer:

The solutions are x=4, y=3. Cashews are $4 per pound and Peanuts are $3 per pound.

Step-by-step explanation:

let x = cashews

let y = peanuts

x + 2y = 10 - rosa's purchase

2x + y = 11 - sabrina's purchase

subtract 2x to isolate 'y'

y = 11 - 2x

x + 2(11 - 2x) = 10

x + 22 - 4x = 10 (Use the distributive property.)

-3x = -12

x = 4.00

Plug this into the original equations to find "y"

2(4) + y = 11

8 + y = 11

y = 3

4 + 2y = 10

2y = 6

y = 3

the solutions are: x = 4. y = 3.

Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and glov
hram777 [196]

Answer:

Luis will pay for three gloves and four bats = $ 270

Step-by-step explanation:

Let the bats be represented by b and gloves by g, then according to the given conditions

3b+ g= $135----equation 1

b+ 2g= $135------equation 2

Subtracting equation 2 from eq. 1 gives

3b+ g= $135----equation 1

<u>-b -2g= -$135------equation 2</u>

<u>2b -g = 0 --------- equation3</u>

2b-g= 0

or 2b= g------ equation4

This means price of 2 bats is equal to price of 1 glove.

Putting value of g in eq. 1 from eq. 4

3b+ 2b= $ 135

5b= $135

b= 135/5= 27

Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54

Luis will pay for three gloves and four bats

= 54*3 + 4*27

= 162+ 108

= $ 270
