Start with 180.
<span>Is 180 divisible by 2? Yes, so write "2" as one of the prime factors, and then work with the quotient, 90. </span>
<span>Is 90 divisible by 2? Yes, so write "2" (again) as another prime factor, then work with the quotient, 45. </span>
<span>Is 45 divisible by 2? No, so try a bigger divisor. </span>
<span>Is 45 divisible by 3? Yes, so write "3" as a prime factor, then work with the quotient, 15 </span>
<span>Is 15 divisible by 3? [Note: no need to revert to "2", because we've already divided out all the 2's] Yes, so write "3" (again) as a prime factor, then work with the quotient, 5. </span>
<span>Is 5 divisible by 3? No, so try a bigger divisor. </span>
Is 5 divisible by 4? No, so try a bigger divisor (actually, we know it can't be divisible by 4 becase it's not divisible by 2)
<span>Is 5 divisible by 5? Yes, so write "5" as a prime factor, then work with the quotient, 1 </span>
<span>Once you end up with a quotient of "1" you're done. </span>
<span>In this case, you should have written down, "2 * 2 * 3 * 3 * 5"</span>
Bly sold 29 scarves last month
<em><u>Solution:</u></em>
Let "x" be the number of scarves sold
Bly made 7 more scarves than she sold
Then, number of scarves made = x + 7
Bly makes fleece scarves and sells them for $11 each
Thus for selling "x" scraves , he will get 11x dollars
Total sales revenue = 11x
number of scarves made = x + 7
The supplies cost her $5 per scarf
Therefore, cost for scarves made = 5(x + 7)
Therefore,
profit = Total sales revenue - cost for scarves made
profit = 11x - 5(x + 7)
profit = 11x - 5x - 35
profit = 6x - 35
Last month, Bly had a profit of $139
139 = 6x - 35
6x = 174
x = 29
Thus Bly sold 29 scarves last month
Your numbers are .17 and .165 meters
Let me explain each digit value:
Lets start with .17
Decimals are like whole numbers where each placement has a digit value
.1 is the tenths place
.07 is the hundredths place
Lets turn to .165
.1 is the tenths place
.06 is the hundredths place
.005 is the thousandths place
When seeing which decimal is larger, go along the tenths place and move along.
So as you can see
, .17 and .165 start with .1 so you can't see which is bigger by this. Now move on to the next digit. Which is larger? .17 or .16? As you should know, 7 is bigger than 6 so that means .17 is larger
Answer: .17 meters is larger than .165 meters
Answer:
Im sorry but there’s nothing on the pic

When you are solving an algebraic one-step equation, the goal is to isolate the variable on one side of the equal sign, two-step equations are the same, but with one more step (hence the name)
