Answer:50
Step-by-step explanation:
15 : 5 = 3
250 : 5 = 3
ADDING THE 2 EQUATIONS TO ELIMINATE Y WE HAVE
-2.98x = -8.94
x = 3
Plug x=3 into first equation:-
-0.18(3) + y = -6.54
y = -6.54 +0.54 = -6
answer x= 3 and y= -6.
3 fours + 3 fours = ..... fours
4+4+4 + 4+4+4 = 24
24÷4 = 6
so 3 fours + 3 fours = 6 fours
Answer:
19
Step-by-step explanation:
The opposite sides are equal, so:
PS = 3y+1
RS = 4y+2
QR = 3y+1
PQ = 4y+2
Therefore, we can set the perimeter 90 = PS+RS+QR+PQ
90 = (3y+1) + (4y+2) + (3y+1) + (4y+2), or,
90 = 2(3y+1) + 2(4y+2)
90 = 6y+2 + 8y+4
90 = 14y + 6
84 = 14y
y = 6
Then, we go back to the question. It's asking for the length of PS. PS = 3y+1, so we plug in 6 for y
3(6)+1
18 + 1 = <u>19</u>
