Answer:
2 horses and 3 ducks
Step-by-step explanation:
2 horses*4 legs=8 legs
3 ducks*2 legs=6 legs
Add both
8+6=14 legs
The way I would approach such a question is to put it into equations.
My first equation would be 16x+19y=478 which represents $16 on ski's per person and $19 on snowboards must add up to $478
My second would be x+y=28 because the number of skis and snowboards rented must add up to 28 so each person has one item.
Next you solve them simultaniously. Gonna use elimination
16x+19y=478 (1)
<span>x+y=28 (2) </span>
16x+16y=448 (3 = equation 2 * 16)
(1)-(3) => 3y=30 y = 10.
So now we know that 10 people rented snow boards. Just sub that into eq (2) and get x = 18. So 10 people got snow boards and 18 ski's.
To check, 10x19 = 190
16x18= 228
190+228=478 which works out perfectly!
Answer:
C
Step-by-step explanation:
By observation, and inspecting the 2 given points closely, we can immediately see that both points have y = -2 as common y-ordinates .
This means that the horizontal line y =-2 joins these 2 points.
Answer C is correct.
1) Lines MR and LQ
2)Lines NP, ML and JK
3)Line KN
4)line JKP
Step-by-step explanation:
9m²+8m-6-7m²-3m+3
first write like terms
9m²-7m2+8m-3m-6+3
second ad subtract the terms
2m²+5m-3
factorize
2m²-m+6m-3
m(2m-1)+3(2m--1)
(m+3)(2m-1)
m=-3. m=1/2
