<span>The first equation is
x + y = 27
For the second equation, there are twice as many girls (y) as boys (x), so you write:
y = 2x
Now you have a system of equations:
x + y = 27
y = 2x</span>
572-335= 237 237 divided by 10 is 23.7 23 tens is the answer
Answer:
<h2><u><em>
8</em></u></h2>
Step-by-step explanation:
12 cars in 15 hours how many cars is in 10 hours
12 : 15 = x : 10
x = 12 * 10 : 15
x = 8
-------------------
check
12 : 15 = 8 : 10
0.8 = 0.8
the answer is good
