The Sum of twice a number and 5 is at most 15. What are the possible values for the number?
NISA [10]
Let's call that number x, twice the number will be 2x, sum of it and 5 is, 2x+5. So if this expression is at most 15, it means, it can be only less than 15 and equal to 15. Let's show this as an inequality.

2x+5\le 15

Let's solve.

2x+5\le 15\\ \\ 2x\le 15-5\\ \\ 2x\le 10\\ \\ x\le \frac { 10 }{ 2 } \\ \\ x\le 5

x\quad \in \quad \left[ -\infty ,5 \right]

If the number is a natural number. The values it can take is, x\quad \in \quad \left[ 0,1,2,3,4,5 \right]

B) Explain how to compute 2 divide 1/4 with a common denominator.
Alex Ar [27]

Answer:

8

Step-by-step explanation:

2 divide 1/4 = \frac{2}{1} : \frac{1}{4}

What we have to do here is find a common denominator for both fractions, in this case 4, and change to equivalent fractions with a denominator of 4.

  • \frac{8}{4} : \frac{1}{4}

Then we divide across. The denominator of the answer will be 1 because the denominators are the same. Divide the numerators and get 8 ÷ 1, wich is just 8.
