Answer:
first you add then you subtract
Step-by-step explanation:
Answer:
x=-3
y=3
Step-by-step explanation:
-27=-9x-18y equation 1
-5y-10x-15=0 equation 2
using equation 2 we have:
-10x -15 =5y
y= -2x -3 equation 3
using equation 3 in equation 1 we have:
-27=-9x-18(-2x -3)
-27= -9x +36x +54
-27-54 =27x
-81 = 27x
so we have:
x= -81/27
x=-3
y= -2(-3) -3
y= 6-3
y = 3
Answer:
A and C divide by 7
Step-by-step explanation:
68÷17=4
357÷17=21
Step-by-step explanation:
Alright so, we need need to lay down the clues we were given
●Ratio of the seats= 2:5
● No.of seats in the circle
●Fraction of seats occupied for the stalls
Now, let us take a closer look at the ratio;
<em>C</em><em>:</em><em> </em><em>S</em><em> </em><em> </em><em>Total</em>
2:5 7
As we can see, the number of parts for the circle is 2 parts.
So ,
2 parts = 528 seats
1 part= 528/2= 264 seats
5 parts= 1 320 seats
7 parts= 264 × 7 = 1 848
Finally,
We can now find the seats occupied by the stalls,
2/3 × 1 320
= 880 seats
Seats of circle + Seats of stall
= 528 + 880= 1408
Percentage Occupancy
=
1408/1 848 × 100
Note: The answer will come in decimal numbers.
It will be,
76.1904761905
or
76.19%
