You always do the operations in parenthese first.
"The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)." -khanacademy . org > ...> order of operations
Answer:
B. (20 ÷ 4 - 2 + 1)
Solved, the equation equals 29.
Step-by-step explanation:
Order of operations: PEMDAS
Parantheses
Exponents
Multiplication
Division
Addition
Subtraction
9 + 5 × 2(20 ÷ 4 - 2 + 1)
The first step would be to do the operations inside the parantheses.
9 + 5 × 2(20 ÷ 4 - 2 + 1)
So,
(20 ÷ 4 - 2 + 1)
There are several operations, so lets look at PEMDAS again..
Okay, so we dont have any exponents, or multiplication inside the parantheses, so next step is divide.
(20 ÷ 4 - 2 + 1)
20 ÷ 4 = 5
So, we replace '20 ÷ 4' with '5'
(5 - 2 + 1)
Next, we add.
(5 - 2 + 1)
2 + 1 = 3
Now, replace '2 + 1' with '3'
(5 - 3)
Now, we just subtract 3 from 5.
5 - 3 = 2
So now our equation looks like this:
9 + 5 × 2(2)
Now, we have to do the parantheses again. But this time we are going to treat the parantheses as a multiplication symbol:
9 + 5 × 2(2) → 2 × 2 = 4
↓
9 + 5 × 4
Now, we have to multiply.
9 + 5 × 4 → 20
↓
9 + 20 = 29
So, when you solve the equation, you get 29.
Based on the graphs of the equations y = –2x + 3 and y = x2 – x + 1, the solutions are located at points:
(0.5, 0.75) and (1, 1)
(–2, 7) and (0, 1)
(0, 1) and (0.5, 0.75)
(–2, 7) and (1, 1)
The solutions of the equations are the point of intersection of the equations
The solutions are located at points (-2,7) and (1,1)
How to determine the solutions?The equations are given as:
y = –2x + 3 and y = x2 – x + 1
Next, we plot the graph of both equations
From the graph of the equations (see attachment), we have the solution to be:
(x,y) = (-2,7) and (1,1)
Hence, the solutions are located at points (-2,7) and (1,1)

Answer:
7/5 y intercept 1
Step-by-step explanation
Answer:
B: slope 5/7 Y-intercept is 1
Step-by-step explanation:
To calculate the slope it is rise orver run
To calculate the Y intercept you look at the graph and where-ever x=0 and y=- is the number.
The slope is 5/7 because the rise is 10 and the run is 14. 10/14 is simplified to 5/7.
the Y intercept is 1 because on the vertical line the line passes through 0,1.
lat a = the length of a car in meters. Let b = the length of the same car in centimeters. which number is greater, a or b? Answer for 100 points.
Answer:
B
Step-by-step explanation:
Centimeters are 100 times bigger than meters, so if you had 1 meter, it would be 100 centimeters. Therefore, centimeters are greater than meters.
110% of 90 is what number a ?
? = 110 over 100
please help
Answer:
90 is the orrect answer because I said so
Step-by-step explanation:
Answer:
The answer is a = 99
Step-by-step explanation:
We can solve this using ratios
First we set up the equation:
[tex]\frac{a}{90}= \frac{110}{100}[/tex]
Then cross-multiply:
[tex]100 * a = 90 * 110[/tex]
Simplify:
[tex]100 * a = 9,900[/tex]
Divide both sides by 100:
[tex]a = 99[/tex]
Ta-Da! The answer is a = 99

PQ = 0 - -0.6
Evaluate the difference
PQ = 0.6
Hence, the distance PQ is 0.6
How to determine the distance between R and Q?From the number line we have:
R = 0.3
Q = 0
The distance is calculated as:

An electronics store has determined that 45% of its customers buy a wide-screen television. describe the model that you could use to find the experimental probability that the next three television-buying customers will buy a wide-screen television
The model that you could use to find the probability is a binomial model with parameters n = 3, X = 3 and p = 0.45.
For each TV bought, there are only two possible outcomes, either it is wide screen, or it is not. The probability of a TV bought being wide screen is independent of any other TV, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
In this problem:
45% of its customers buy a wide-screen television, hence p = 0.45.The experimental probability that the next three television-buying customers will buy a wide-screen television is P(X = 3) when n = 3.More can be learned about the binomial distribution at https://brainly.com/question/24863377

Maddy has a coupon for bananas. Bananas normally
cost $0.49 per pound. Maddy wants to buy 8
pounds of bananas for her team. She has a coupon
for 5 cents off per pound.
If she uses the coupon, how much will she pay?
Answer:
$3.52
There are two ways you can solve this problem.
1. Take 5 cents off before multiplying.
Since the coupon takes 5 cents off per pound, you can subtract 5 cents off 49 cents.
$0.49-$0.05= $0.44
Now multiply $0.44 by the 8 pounds.
$0.44 (8) = $3.52
2. Take the 5 cents off after multiplying
You can multiply the 5 cents by 8, to find the total money off the bananas. Then subtract that from the total cost.
$0.49 (8) = $3.92 -> Total cost with no coupon
$0.05 (8) = $0.40 -> Total money off
Subtract the two totals.
$3.92 - $0.40 = $3.52
