Answer:
Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was 
on Monday. So the decrease in temperature from Monday to Thursday will be 
.
We have been given that the swimming pool is open when the high temperature is higher than 
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:
Therefore, the inequality can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
Answer:
The Answer is 29/18 and in mixed form it is 1 11/18
Step-by-step explanation:
Steps for adding fractions
Find the least common denominator or LCM of the two denominators:
LCM of 9 and 6 is 18
Next, find the equivalent fraction of both fractional numbers with denominator 18
For the 1st fraction, since 9 × 2 = 18,
7
9
=
7 × 2
9 × 2
=
14
18
Likewise, for the 2nd fraction, since 6 × 3 = 18,
5
6
=
5 × 3
6 × 3
=
15
18
Add the two like fractions:
14
18
+
15
18
=
14 + 15
18
= 29/18
So, 7/9 + 5/6 = 29/18
In mixed form: 1 11/18

Step-by-step explanation:
1) would be opposite of a sum property
2) it would be D
7x + 3y = -12
2x + 5y = 38
5y = -2x + 38
y = -2x/5 + 38/5
7x + 3•(-2x/5+38/5) = -12
29x/5 = -174/5
29x = -174
x = - 6
x=-6
y = -2x/5+38/5
y = -(2/5)(-6)+38/5 = 10
x=-6
y=10
