Hello from MrBillDoesMath!
Answer:
8
Discussion:
Let the number be "n". Then the question states that
3n - 15 = (n/2) + 5 => multiply both sides by 2
6n - 30 = n + 10 => subtract n from both sides
5n - 30 = 10 => add 30 to both sides
5n = 30 + 10 = 40 => divide both sides by 5
n = 40/5 = 8
Thank you,

Answer:
No
Step-by-step explanation:
(2,2) isn't but (6 1/2, -2) is because that is where they intercept
Answer:
try 10 km/h as the base speed
Step-by-step explanation:
We need to find the lowest common multiple...
multiples of 14 are : 14,28,42,56,70,84,98,112,126,140,154
multiples of 20 are : 20,40,60,80,100,120,140
so the lowest common multiple is 140....so thats 140 minutes....= 2 hrs 20 minutes....from 8:00 = 10:20
so they will both leave at the same time of 10:20 a.m. <==
The new ratio of the number of cookies in Jar A to the number of cookies in Jar B in the end is 5 : 19
<h3>How to find ratio</h3>
Ratio of jar A to jar B = 3 : 8
Jar B = 1/2 of A + B
= 1/2 × 3 + 8
= 3/2 + 8
= (3+16) /2
= 19/2
Jar A = 3 - 1/2
= (6-1) /2
= 5/2
New ratio of jar A to jar B = 5/2 : 19/2
= 5/2 ÷ 19/2
= 5/2 × 2/19
= 5/19
= 5 : 19
