Sajia has 30 Books in her library. she sold 9 books at the thrift store on Saturday. Write and solve and inequality to determine how many more books she can sell if she comes back on sunday?

Answers

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is $9 + x \leq 30$

Solution:

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

We can write a inequality as:

$\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }$

$9 + x \leq 30$

Now moving 9 from L.H.S to R.H.S we get,

$x \leq 30 - 9$

On solving 30 - 9 = 21,

$x \leq 21$

So Sajia can sell 21 books she can sell if she comes back on sunday

Juan always saves the same amount from his weekly allowance. The table shows how much he has saved at different times.Which equation represents the situation?

Juan’s Savings

Weeks
3, 6, 9, 12
Amount saved 19, 28, 37, 46

A.

y – 3 = −3(x – 19)

B.

y – 28 = 3(x – 6)

C.

y + 9 = −3(x + 37)

D.

y + 46 = 3(x – 12)
I'm pretty sure it's B.

Answers

Juan always saves the same amount from his weekly allowance, then the equation which represents the situation is y -28 = 3(x - 6). Therefore, option B is correct.

What is an equation?

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. It is clear that a statement is not even an equation if there is no "equal to" sign in it.

A solution is obtained by entering 3 (weeks) for "x" and 19 (savings made) for "y," which results in the equation 0=0.

You're correct, it is B. If you plug in 3 (weeks) in for "x" and 19 (amount saved) for "y" you will get 0=0, which is a solution.

Math prob in textbook: the price of a liter of coke increased from 1.09 to 1.29. What was the percent of increase? I know how to do it, but I don't understand the answer. I got .18348624... On and on. The book said approximately 18.3% how did they get that? Where did the decimal come from? How would I round that non ending decimal to a percent money-wise?

Answers

You did every bit of the tough part, and did it masterfully.

Now, go back a few months or a year in your memory, to the time when
you learned how to express a number as a percentage. Do you remember ?

To change a number to a percentage, either multiply it by 100, or move the
decimal point two places that way ===> . (The same thing.)

The number you got was correct. When you increase 1.09 to 1.29, you have
increased the 1.09 by 0.1834862... of it.

What percent of 1.09 is 0.1834862... of it ?

Change the number 0.1834862... to a percent . . . . . 18.34862... percent.

Usually, nobody cares about all those decimal places, so you usually just
round it to the nearest 0.1 percent, or even the nearest whole percent.

What did the book say ? Approximately 18.3% ? OK. Round 18.34862...% to the
nearest 0.1. That's 18.3% .
