<span>7a+(4+5a)=12a+4
The first step to this is to simplify both sides of the equation.
</span><span>You have to combine all of the like terms first...
(7x + 5x) + (4) = 12x + 4
12x + 4 = 12x + 4
Now the second step is to subtract 12x from both sides....
</span>12x + 4 = 12x + 4
-12x -12x
4 = 4
Now you will subtract four from both sides and get....
0=0

= 500,000 + 20,000 + 7,000 + 500 + 10 + 9
= (5) * 100,000 + (2) * 10,000 + (7) * 1,000 + (5) * 100 + (1) * 10 + (9) * 1
= (5) * 10⁵ + (2) * 10⁴ + (7) * 10³ + (5) * 10² + (1) * 10¹ + (9) * 10⁰
Answer:
Thomas can buy 4 strands.
Step-by-step explanation:
We need to round $11.86 to the nearest dollar, which is $12.
Now we ask ourselves, "how many times does 12 go into 50 without going over?"
12 × 4 = 48
12 can go into 50 4 times.
