Answer:
1:4
Step-by-step explanation:
First we need to find the total number of fish
21 goldfish + 7 tetra fish = total fish
28 fish = total fish
tetra: total
7: 28
We can divide each of these numbers by 7
7/7:28/7
1:4
is the ratio.
Answer: There are 7 tetra fish and the total is 28 fishes.
Step-by-step explanation:
Answer
46.24
Explanation
n² = n × n
∴ (-6.8)² = (-6.8) × (-6.8)
= 46.24
The answer is positive since (-1)×(-1) = 1.
-6.8^2
You can do this with a calculator or pen and paper.
With a calculator;
-6.8 squared = 46.24 (Notice that the answer is positive!)
40.00 - 19.50 = 20.50
20.50 ÷ by 2 = 10.25
each video cost
Geno now wants to write an equation to solve the problem. He let g = cost of a video game.
Which equation can be used to find the cost of each video game?
A. 2g = 19.5
B. 2g + 40 = 19.5
C. 2g –19.5 = 40
D. 19.5 + 2g = 40
