Answer:

7/15

Step-by-step explanation:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 4 by 3, and get 12.

Then we multiply 1 by 5, and get 5.

Next we give both terms new denominators -- 5 × 3 = 15.

So now our fractions look like this:

−

Step 2

Since our denominators match, we can subtract the numerators.

12 − 5 = 7

So the answer is:

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 7. So we're done reducing.

What is 0.7, 7/9, 7/8 in order from greatest to least

Sphinxa [80]

Simple...

change them all into fractions or decimals...

0.7---> 0.7

$\frac{7}{9}$ -->>0.77

$\frac{7}{8}$ --->>0.875

Ordering from greatest to least....

0.875-->>0.77-->>0.7

$\frac{7}{8}$ -->> $\frac{7}{9}$ -->>0.7

Thud, your answer.

You are choosing between two health clubs. Club A offers membership for a fee of $ 28 plus a monthly fee of $ 22. Club B offers

Mazyrski [523]

Answer: 2 months, Total cost= $72

Step-by-step explanation:

Let x denote the number of months then

For Club A fee= 28+22x

For Club B fee= 16+28x

Equating both we get

28 + 22x= 16+28x

28-16= 28-22x

12= 6x

x= 2

So after 2 months the fee will be same i.e. 28+22(2)= $72

Please someone explain how to solve this piecewise function!!!! Im super confused

Xelga [282]

Answer:

From top to bottom:

$0, 1, 2, -8, -8$

Step-by-step explanation:

We are given the piecewise function:

$g(x) = \left\{ \begin{array}{ll} 0.5x+1 & \text{if } x \leq 2 \\ -8 & \text{if } x > 2 \end{array} \right.$

Row 1:

We want to find g(-2).

Since -2 is less than (or equal to) 2, we will use the first equation. Thus:

$g(-2)=0.5(-2)+1=-1+1=0$

Row 2:

Likewise, 0 is less than or equal to 2. We will continue to use the first equation:

$g(0)=0.5(0)+1=1$

Row 3:

2 is not less than 2 but it is equal to 2. So we will continue to use the first equation:

$g(2)=0.5(2)+1=1+1=2$

Row 4 and 5:

Both 4 and 6 are greater than 2. Thus, we will use the second equation. Therefore:

$g(4)=-8\text{ and } g(6)=-8$

It takes 12 buckets of water to fill a fish tank. If chloe uses scoops equal to 1/4 of a bucket, how many scoops are needed to f

Bas_tet [7]

Answer: 48

Step-by-step explanation:

From the question, we are informed that it takes 12 buckets of water to fill a fish tank. We are further told that Chloe uses scoops which are equal to 1/4 of a bucket.

The number of scoops that are needed to fill the whole tank would be:

= 12 ÷ 1/4

= 12 × 4

= 48
