Answer:
60$
Step-by-step explanation:
if 4$ is per year 20 ÷4 is 5, 5 years have passed and if 10 uears after the champion ship it will be 60 because 4 × 10 is 40 plus the 5 years since it was 20 therefore 20+40 =60
Lets find the unit rate of both of the shirts.
5 for 63
4 for 54
63/5 = 12.60
54/4 = 13.50
Now we have our unit rates!
Greg = $12.60 per shirt
Zachary = $13.50 per shirt
Greg's shirt were cheaper than his brothers, so it has a better cost.
Answer:
Theorem.
Step-by-step explanation:
Postulate/Axiom: Can't be proven or disproven.
Definition: Defines a term. Can be proven.
Theorem: Can be proven.
"Proof" (informal but it works): Triangle has 180°, that means two angles will be less than 180°. Right angles are 90°, that means two 90° angles add up to 180°. Something that is less than 180° is less than 180°.
This statement is provable, but doesn't necessarily define anything.
If Bonnie spent 1/5 of $1,000 on traveling arrangements, she spent $200 on traveling arrangements.
1/5×1,000 = 200
Then she spent 2/3 of the remaining amount at the hardware store. The remaining money is $1,000-$200.
1,000-200 = 800
2/3×800 = 533 1/3
Since we are dealing with money here, 533 1/3 would become $533.33.
Then she treated her family with lunch with the remaining money. Well, the money she had left would be $1,000-$533.33.
1,000-533.33 = 466.67
So she had $466.67 remaining.
Well, after she spent that portion of $466.67 for a lunch, she had $300.50... meaning she spent $166.17 on the lunch.
466.67-300.50 = 166.17
So... Bonnie spent $166.17 on the lunch.
