Order of operations.

Parentheses

Multiplication
Division
Addition
Subtraction

We must do parenthesis first.

72 - 13 = 59

We have now
20 + 15(59) - 67 + 6
20 + 885 - 67 + 6
905 - 67 + 6
905 - 61
844

Hope this helped! If you have any questions then leave a comment.

Good morning

20+15(72-13)-67+6

= 20+15(59)-67+6

= 20+885-67+6

= 905-67+6

= 838+6

= 844


I hope that's help !


Happy Sunday :)

What is the product? (3x-6) (2x^2 -7x+1)
STALIN [3.7K]

<u>Answer-</u>

\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6

<u>Solution-</u>

Given the two polynomials are 3x-6, 2x^2 -7x+1

So their product will be,

=\left(3x-6\right)\left(2x^2-7x+1\right)

Distributing the Parentheses,

=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1

Applying minus-plus rules,

=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1

Simplifying further,

=6x^3-33x^2+45x-6

The half-life of caffeine in a person’s bloodstream is about 6 hours. If a person’s bloodstream contains 80 milligrams of caffei
Luda [366]
To calculate the remaining caffeine, we use the radioactive decay formula which is expressed as An = Aoe^-kt where An is the amount left after t time, Ao is the initial amount and k is a constant we can calculate from the half-life information. We do as follows:
 at half-life,
ln 1/2 = -k(6)
k = 0.12/hr

An = 80e^-0.12(14)
An = 15.87 mg

In the U.S thirteen of twenty cans are recycled. What % of cans are recycled?
madam [21]

A percent is how many out of 100.

13/20 is how many out of 100?

You multiply the top and bottom by 5, as 5x20 is 100

13x5 is 65

Therefore, 65 out of every hundred cans, or 65%, are recycled

Use the information given to enter an equation in standard form.
Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17
