Can someone help me with those questions? (Try your best plzz)

Step-by-step explanation:

1. 34 animals because of 34 heads.

94 legs: 4 per cow, 2 per chicken

x= # of cows

y= # of chickens

so x+y=34

4x+2y=94

Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.

which is 2x=26. so x=13. Since x+y=34, 13+y=34.

Therefore, y=21

13 cows and 21 chickens.

2. lets say

pizza=y

soda=x

6x+x=14 combine like terms

7x=14 divide both sides by 7

x=2

So a soda is $2.

6*2=12. So the pizza is $12.

12+2=14. So it's correct.

3.

# of DVDS=x

# of Bluray= y

11x+17y=95

x+y=7

dvds-4

blu-ray-3 (I just did trial and error, but it's correct)

4.  

# of 2-points= x

# of 3-points= y

2x+3y=18

2(6)+3(2)=18

so 6 two-point shots and 2 three-point shots.

5.

12 coins are quarters and 14 are dollar coins.

let q stand for the number of quarters

and 26 coins in total

26-q= dollar coins

x=dollar coins too

so its 1x+.25(26-x)=17

1x+6.5-0.25x=17

.75x+6.5=17

.75x=10.5

x=14

17-14=3

3*4= 12 since 4 quarters in a dollar.

answer: 2530
