Answer:
- It has taken Jake about 40 minutes to finish his Spanish homework.
Step-by-step explanation:
<u>We know that:</u>
- Homework = 4 hours = Spanish + Math + Science + History
- Spanish = 4 hours x 1/6
- Math = 4 hours x 1/4
- Science = 4 hours x 1/4
- History = 4 hours x 1/3
<u>Work:</u>
- Spanish = 4 hours x 1/6
- => 2 hours x 1/3
- => 2/3 hour
- => 2/3 x 60 minutes
- => 40 minutes
Hence, it has taken Jake about 40 minutes to finish his Spanish homework.
Answer:
7d +d +d=45
Step-by-step explanation:
The length shown for the green line is shown as 45 therefore the black line also has 45
to prove your answer:
7d + d + d = 45
9d = 45
you need to get the letter d on its own so you
9d ÷9 = 45 ÷ 9 (what you do on the one side,you do on the other)
d = 5
*substitute
5 + 7(5) + 5
= 5+ 35 + 5
= 40 +5
= 45
