So 5a=cost of adults
3s=cost of students
a+s=1142
5a+3s=4326

a+s=1142
subtract s from both sdies
a=1142-s
subsitute 1142-s for a
5(1142-s)+3s=4326
5710-5s+3s=4326
5710-2s=4326
subtract 5710 from both swides
-2s=4326-5710
-2s=-1384
dividee both sides by 2
-s=-692
multiply -1
s=692
692 students
subsittue

a+692=1142
subtract 692
a=450

s=692
a=450

A birdbath is filled to the top. On Day 1, the volume of water in the bowl decreases by 7/8 cup. On Day 2, the volume in the bow
Romashka-Z-Leto [24]

Answer:

-1 5/8

Step-by-step explanation:

Let the total amount in the bowl be x;

If on Day 1, the volume of water in the bowl decreases by 7/8 cup, the remaining water will be;

x - 7/8

If on day 2, the volume in the bowl decreases by 3/4 cup, the remaining volume of water after the second day will be;

= x - 7/8 - 3/4

= x - (7-2(3))/8

= x - (7+6)/8

= x - 13/8

This shows that the total change after the two days is -13/8

As a mixed fraction;

-13/8 = -1 5/8

0.31 repeating as a fraction
sukhopar [10]
I believe its 31/100! <span>To write 0.3111 as a fraction you have to write 0.3111 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.</span>
