Answer: .
Step-by-step explanation:
1. 1st number be x, 2nd number be y
Adding 5 times the first number and 8 times the second number gives a total of -13
so 5x+8y=-13
Adding 5 times the first number and 10 times the second number gives -15
so 5x+10y=-15
subtracting the above two eqns
(5x+8y)-(5x+10y) = -13-(-15)
-2y=2
y=-1
put back in first eqn 5x+8(-1)=-13
5x=-5
x=-1
2. area of town A = 1500
every year, the area of the town decreases by 7%
so after 1 year, A=1500*(1-7%)=1500*(0.93)
after x years, A=1500(0.93)^x
Answer:
B) -5 and 5
Step-by-step explanation:
Integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. One integer is negative and the other is positive.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
Let's work on the product given.
- => 4/5 x 11/9
- => 4 x 11/9 x 5
- => 44/45
Now, let's verify all options.
<u>- Option A -</u>
- Statement: Because 11/9 is greater than 1, the product of 4/5 and 11/9 is less than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because the result we got from the product is greater than 4/5 while the statement states that the result should be less than 4/5. Hence, this is incorrect.
<u>- Option B -</u>
- Statement: Because 11/9 is less than 1, the product of 4/5 and 11/9 is greater than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because 11/9 is not less than 1.
<u>- Option C -</u>
- Statement: Because 11/9 is less than 1, the product of 4/5 and 11/9 is less than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because 11/9 is not less than 1.
<u>- Option D -</u>
- Statement: Because 11/9 is greater than 1, the product of 4/5 and 11/9 is greater than 4/5.
- Correct/Incorrect: The statement is correct.
- Reason: This is because 11/9 is greater than 1 and the product is greater than 4/5. Hence, this statement is correct.
<u>Conclusion:</u>
We can now conclude that statement D is correct.
