Answer:
22 and a half weeks
Step-by-step explanation:
We are told that Nilda owes $250 and has been earning $25 per week to catch up and start saving.
Also, Karla has saved $200 and has been saving an extra $5 per week to slowly build her savings.
Let the number of weeks they save for be represented as x.
Therefore, for them to have the same amount of money after x weeks,
25x - 250 = 200 + 5x
The left hand side represents Nilda's situation (250 is being deducted because she owes $250) while the right hand side represents Karla's situation (the 200 is added because she already owns $200).
Solving for x:
25x - 250 = 200 + 5x
Collecting like terms:
25x - 5x = 250 + 200
20x = 450
x = 450 / 20 = 22.5 weeks
Hence, they would both need to save for 22 and a half weeks to have the same amount of money.
Answer:
0
Step-by-step explanation:
- Plot each point on the graph corextly using (x,y).
- The line should go verticle
- Since x doesnt change, there is no slope / the line will go up and down infinate
Answer:
The ratio between them is approximately 
, therefore the correct answer is A.
Step-by-step explanation:
In order to calculate the ratio of the diameter of the Sun to the diameter of the Earth we will first represent the Earth's diameter as a scientific notation, to do this we will add one to the power of ten for every time the comma walks to the left until there's only one number to the left. This is done to make the division easier,
The ratio is given by the Sun's diameter divided by the Earth's, as shown below:
The ratio between them is approximately , therefore the correct answer is A.
