Answer
write an expression for the total number of fish in the store using the expression k .
To proof
As given in the question
A pet store has k tanks of fish .
Each tank has 28 fish.
Total number of fish in the store = 28k.
This expression is written above represented the total number of fish in the store using expression k .
Hence proved
Step-by-step explanation:
Supplementary angles equal 180°
1. Let the two angles be x and y
then y = 4x + 10
x + y = 180
x + (4x + 10) = 180
5x + 10 = 180
5x = 180 - 10
5x = 170
x = 170 / 5
x = 34
x = 34y = 146
2. if the two angles are equal then divide 180 by 2 to get 90
3. 180 - x = 3(90 - x)
180 - x = 270 - 3x
2x = 90
x = 45
4. 180 - x = 2x - 12
180 - 12 = 2x + x
168 = 3x
x = 56
Answer:
d. 0.6 > 4/7
Step-by-step explanation:
a. 1.5 > 5/3
From part a, it is given that 1.5 is greater than 5/3
changing 5/3 to decimal figure, we get 1.67
Thus, the claim that 1.5 > 1.67 is not valid because 1.67 is greater than 1.5
b. 2.5 < 0.25
given that 2.5 is less than 0.25 is not valid because 2.5 is greater than 0.25
c. 0.07 > 7/10
if we convert 7/10 to decimal figure, we get 0.7
the claim that 0.07 is greater than 0.7 is not valid because 0.7 is greater than 0.07
d. 0.6 > 4/7
If we convert 4/7 to decimal figure, we get 0.57
Therefore, the claim that 0.6 is greater than 0.57 is accurate and valid
Hence, Option d is the correct answer.
I think the answer is 15π inches ² or 15
A=b+1
a=2b+9
b+1=2b+9
-b from both sides
1=b+9
-9 from both sides
-8=b
b+1
-8+1
-7
You can check your answer...
2b+9
2(-8)+9
-16+9
-7
The smaller is -8 and the larger is -7
