N + (n+1) + (n+2) = 63
The integers are 20,21,and 22.
The largest is 22.
Answer:
19
Step-by-step explanation:
5 ÷ ¼ = 20
20 - 1 = 19
One less because the last ¼mile is the end of the walk way so no marker needed
Instantaneous speed is the magnitude of instantaneous velocity.
The first thing you should do is to<span> divide the total cost by the unit cost you have got: </span><span>(2y^2 + 6) / (y^2 - 1) </span>
Then just use simple math by plugging in the value y=3
(2*3²+6): (3²-1)= 24:8 = 3 which is the nubmer of the bought notebooks.
<span>In total he spent $24 on notebooks that cost $8.</span>
Answer:
x = -29/11 , y = 5/11
Step-by-step explanation:
-x+3y=4 ,..........(1)
3x+2y=-7 ............(2)
Solve simultaneously using elimination method
Multiply equation 1 by 3
It gives
-3x + 9y = 12
3x + 2y = -7..........(2) , add both equations
--------------------------
11y = 5
Divide both sides by 11
y = 5/11
Put value of y into equation (2)
3x +2y = -7
3x + 2(5/11) = -7
3x + 10/11 = '-7
Subtract 10/11 from both sides
3x +10/11 - 10/11 = -7 - 10/11
3x = -87/11
Divide both sides by 3
3x/3 = -87/11 ÷ 3
x = - 87/11 × 1/3
x = -29/11
Therefore x = -29/11 , y = 5/11
