Answer:
<u>The sum of their ages now is 13</u>
Step-by-step explanation:
Dally's age = x
Dilly's age = x - 7
In 4 years time Dilly will be half Dally’s age, therefore:
Dilly's age plus four equals to half of Dally’s age plus four,
replacing with the values and variables we know:
x - 7 + 4 = (x + 4) /2
x - 3 = (x + 4) /2
2x - 6 = x + 4 (Multiplying by 2 at both sides)
2x - x = 4 + 6 (Like terms)
x = 10 ⇒ x - 7 = 3
<u>The sum of their ages now is 13 (10 + 3)</u>
Answer:
Jake scored more on the spelling quiz. 80% is more than 68% so therefore he scored more on the quiz. To find 80% and 68%, you can use a percent of proportion or divide and multiply by 100.
Step-by-step explanation:
To find the percent of a score, you divide.
17/25 (division) = 0.68
0.68 is a decimal so to make it a percent you multiply by 100 = 68%
Or you can do it with fractions:
17/25 = ?/100: 68
16/20 = 0.8
Again, 0.8 times 100 = 80%
Or you can do it with fractions:
16/20 = ?/100: 80
He scored more on the spelling quiz, I hope this helps (justification on the answer).
