If seven pencils cost $.84 find the cost of 10 pencils?
Lets solve this!
To solve this question, you need to first divide .84 ÷ 7 which gives you the answer 0.12. Then multiply 0.12 with 10 which gives you the cost of 10 pencils. 0.12 is the cost of only one pencil.
Lets forms this into statements ---
Cost of 7 pencils = $ .84
Cost of 1 pencil = $ 0.12
Cost of 10 pencil equals = .84 ÷ 7 = 0.12
= 0.12 × 10 = 1.2
Cost of 10 pencils is $1.2
Hope I helped (:
Have a great day!
Ok, so I’m pretty sure that would be a little less than 7 minutes because if 5 min is -150 degrees then 1 min is around 25 degrees. So around 7 min would be the answer.
Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
