12(5-5)+3x5 evaluate the expression

Mathematics

4 0

Answer:

Using PEMDAS we can see that P or parenthesis is first so we would subtract 5 from 5 in the beginning. That would result in a 0 which would then get multiplied with 12 to still have 0.

$12(5-5) + 3 * 5$

$12(0) + 3 * 5$

$0 + 3 *5$

Now that we completed that part, the only thing that we have left to do is to multiply the last two numbers, 3 and 5.

$3*5$

$15$

Therefore, our final solution is 15.

Hope this helps!

Which fraction is equivalent to StartFraction 2 Over 6 EndFraction? StartFraction 3 Over 7 EndFraction, because StartFraction 2

irinina [24]

Question:

Which fraction is equivalent to $\frac{2}{6}$ ?

- $\frac{3}{7}$ because $\frac{2}{6}= \frac{2 + 1}{6 + 1}$

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{12}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{8}$ because $\frac{2}{6}= \frac{1}{2} = \frac{2+1}{6+2} = \frac{3}{8}$

Answer:

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

Step-by-step explanation:

Two fractions are said to be equal if and only if they give the same value when simplified.

The equivalent of $\frac{2}{6}$ is as explained in the selected option;

First, divide numerator and denominator by 2

$\frac{2/2}{6/2}$

Then simplify

2/2 = 1 and 6/2 = 3; So;

$\frac{2/2}{6/2} = \frac{1}{3}$

Multiply numerator and denominator by 3

$\frac{1*3}{3*3} = \frac{3}{9}$

Hence, $\frac{2}{6}$ is equivalent to $\frac{3}{9}$

Jason and Jeremy work together at a juggling-ball factory. Jason lives 25 miles away from the factory and drives at 60 miles per

postnew [5]

Jason arrives at the factory first

It takes 5 minutes until the other person arrives

Solution:

The time taken is given by formula:

$Time\ taken = \frac{distance}{speed}$

Jason lives 25 miles away from the factory and drives at 60 miles per hour

Therefore, time taken by Jason is:

$Time\ taken = \frac{25}{60}\ hour$

Convert to minutes

1 hour = 60 minutes

Therefore,

$Time\ taken = \frac{25}{60} \times 60\ minutes = 25\ minutes$

Jeremy lives 35 miles away from the factory and drives at 70 miles per hour

Therefore time taken by Jeremy is:

$Time\ taken = \frac{35}{70}\ hour\\\\Time\ taken = \frac{35}{70} \times 60\ minutes\\\\Time\ taken = 30\ minutes$

They leave their houses at the same time

25 minutes < 30 minutes

Thus Jason arrives first

Jason arrives to the factory in 25 minutes

Jeremy arrives to the factory in 30 minutes

⇒ 30 - 25 = 5 minutes

Jeremy arrives after Jason by 5 minutes

It takes 5 minutes until the other person arrives
