We know it's for helping students so chill but I'll help, the number is 9 million and it's in the millions. You see all you have to do is classify the place value and say what the number is called.
Answer:
add 3 to both sides of the equal sign
Step-by-step explanation:
to solve the equation you would have to add three
that is because you have to do inverse operations
and you would add because the opposite of subtracting is adding
so solving it would look like this
x - 3 = 12
+3 +3
x = 15
this is how you check the answer:
15 - 3 = 12
+3 +3
Marcus had 5 horses and Rachel had 5 times more. She had to divide them into 5 stalls. How many are in each stall?
3/20 = 1.5/10 = 15/100
Hope this helps!
15x-3y=12
<u>y=5x—4
</u>I'm also not sure what your question is, but this is what I got by solving it like a regular equation.
15x-3(5x-4)=12
15x-15x+12=12
0=12-12
0=0
4x-y=-4
<span><u>-8x+2y=2</u>
</span>
-y=-4-4x /: (-1)
y=4+4x
-8x+2y=2
-8x+2(4+4x)=2
-8x+8+8x=2
0=-6
