Answer for 1) One
Answer for 2) Two
Answer for 3) A prime number has only two factors, one and two.
Answer for 4) Two is the smallest prime number [I don’t understand that wording so that’s the best I can come up with]
Answer for 5) There are eight prime numbers less than 20.
Answer:
x=40 degrees
Step-by-step explanation:
3x=120 (vertical angles)
solve: 3x=120
x=40
First multiply the equation by 5 to get y by itself.
Then subtract 35 from each side to get the integer by itself.
So, final answer:
<span>0.5x - 0.1 = -2.9
When you multiply each side of an equation by the same number,
you don't change the equation or its solution. If you want to get rid
of the decimals, you could multiply each side by 10. Then the
equation is
5x - 1 = -29
You should be able to solve that without help.
But I'm about to take your points, so here's
how to solve that equation:
</span><span><span>5x - 1 = -29
Add 1 to each side: 5x = -28
Divide each side by 5 : x = -28 / 5
Simplify the solution: x = -5 and 4/5 .
Again ... this is the same solution as the original equation
if we hadn't gotten rid of the decimals.
