When solving (x − 15) = −4, what is the correct sequence of operations? (5 points)

1 answer:

I'm not sure if you forgot to put a number before the parentheses or something, because this doesn't look right. I am going to help you in the best way I can think of.

You can always solve equations easier using PEMDAS.

It stands for parentheses, exponents, multiplication, division, addition, and subtraction.

It is in that order, because that is the order you are supposed to do it in.

Hoped I ended up helping you some! :)

What is a unit rate?

iragen [17]

When ratesss are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit ratessss. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.....

It cost $36.75 for three tickets to visit the science center. It cost $51 for 4 tickets to visit the zoo. Which attraction will

Ber [7]

Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6

Explain why it makes sense for this situation to have a linear equation

IgorC [24]

Answer:

The line of best fit for your specific question is a linear equation.

Step-by-step explanation:

A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.

If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.

If the data plots was a quadratic, it would be very hard to draw a line of best fit.

Linear equations can easily be identified in a graph because it is a straight line.

Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2

A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.

Take these examples: y = $3x^2+5x+2$ or y= $-2x^2+10x+30$

Keisha is reading a 350 page book at a rate of 27 pages per day. Use a point-slope equation to determine how many pages she will

Scrat [10]

Answer:

She will still have 80 pages left to read after 10 days.

Step-by-step explanation:

Keisha is reading the book at a rate of 27 pages per day. The book has 350 pages. So , after x days , the no. of pages remaining to read is,

$y = 350 - 27 \times x$ ---------------(1)

Here, the given value of x is 10. So, putting x = 10 in (1) we get,

$y = 350 - 27 \times 10$

= 80

Half of the product of two consecutive numbers is 105. Which equation can be used to solve for n, the smaller of the two numbers

Illusion [34]

Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.
