How to do it:
Start by finding like terms (terms with the same variable)
5b and 2b are like terms because they have the same variable (b)
10 and -4 are like terms because they both have no variable
Combine like terms
5b+2b=7b
10-4 =6
So the answer is 7b+6! Hope this helps my friend. :)
Answer:
7b + 6
Step-by-step explanation:
Given expression,
→ 5b + 10 + 2b - 4
Let's solve the expression,
→ 5b + 10 + 2b - 4
→ (5b + 2b) + (10 - 4)
→ 7b + 6
Hence, answer is 7b + 6.

a town's population has been growing linearly. in 2003, the population was 59000, and the population has been growing by 1700 people each year. write an equation for the population x years after 2003.
Answers
Answer:
The population after x years will be P = 29000 + 700x
Let the population after the years be represented by P
Population of the town in 2003 = 29000
Annual increase in growth = 700
Then, the population after x years will be:
P = 29000 + 700(x)
P = 29000 + 700x
Therefore, the population will be P = 29000 + 700x.

A plane flew 216 miles from Bristol airport to Leeds Bradford airport. It had an average speed of 162mph and arrived at 18:15. Work out what time the plane left Bristol airport. Give your answer using the 24 hour clock.
Answers
The plane left Bristol airport at 16:55.
This is a problem from time and distance. We can solve this problem by following a few steps.
We have to know the relation between time, speed, and distance. The relation is denoted as,
t = s/v; t is denoted as time interval, v is denoted as velocity or speed in this case and s is denoted as displacement or distance.
We have to find the time. Here velocity is 162 mph and the total distance between Bristol airport to Leeds Bradford airport is 216 miles.
t = 216 miles/ 162 mph = 1.33 hour = 80 minutes.
Therefore the plane left Bristol airport is, ( 18 hours 15 minutes - 80 minutes) = 16 hour 55 minutes = 16:55

according to a study by the centers for disease control and prevention, about 33% of u.s. births are caesarean deliveries. suppose seven expectant mothers are randomly selected. what is the probability that at least one of the expectant mothers will have a caesarean delivery?
Answers
The probability that at least one of the expectant mothers will have a cesarean delivery is 0.9394.
What is probability?Probability is the likelihood that something will happen. Based on the information, about 33% of u.s. births are cesarean deliveries.
The number (n) is also given as 7.
p = 33% = 0.33
n! / (n – r)!
N is the number of things you are choosing from,
r is the number of items.
P(x:n,p) = ⁿCˣ x pˣ(1-p)ⁿ⁻ˣ
n is the number of trials (occurrences)
X is the number of successful trials
p is probability of success in a single trial
ⁿCₓ is the combination of n and x
Therefore, the probability will be:
= 1 - P(no mother will have a Caesarean section)
= 1 - P(X = 0)
= 1 - ⁷C₀ (0.33)^0(0.67)^7
= 1 - 0.0606
= 0.9394

Graph the line that represents each linear equation does anyone know a 2d version I can see instead of words to explain it?
Answers
The graph of the first linear equation:
y = x + 3
Can be seen in the image at the end.
How to graph the linear equation?Let's graph the first line, which is:
y = x + 3.
To graph it, we need to find two points on the line, to find these, we can evaluate the linear equation in two values of x.
Using x = 0 we get:
y = 0 + 3
y = 3
So we have the point (0, 3).
Using x = 1, we get:
y = 1 + 3
y = 4
So we have the point (1, 4)
Now we can graph these two points on the same coordinate axis and connect them with a line. Like in the example below.

Step-by-step explanation: -3 raised to the power of 3 is written (-3) 3 = -27. Note that in this case the answer is the same for both -3 3 and (-3) 3 however they are still calculated differently. -3 3 = -1 * 3 * 3 * 3 = (-3) 3 = -3 * -3 * -3 = -27.

Carmen invested her saving in fund B as $11,000.
What is termed as the investment?Investing entails allocating capital (money) to tasks or projects that are anticipated to generate a profit over time.The type of return generated is determined by the project or asset; for example, real estate can generate both rents as well as capital gains; numerous stocks pay semiannual dividends; and bonds typically pay regular interest.For the given question;
Let 'x' be the amount invested by Carmen in fund B.
The, the amount invested in fund A is x - 5000.
The profit on fund A is 2% = 2%(x - 5000).
the profit on fund B is 5% = 5%(x).
Then, the total profit is $670.
The equation will be .
2%(x - 5000) + 5%(x) = 670
2(x - 5000)/100 + 5(x)/100 = 670
2x - 10,000 + 5x = 67,000.
Further simplifying.
7x = 67,000 + 10,000
7x = 77,0000
x = 11,000
Thus, amount invested in fund B is $11,000.

find w, given that the line joining a(3,4) to b(w,-5) is perpendicular to a line with slope -2/3
Answers
Answer:
w is -3
Step-by-step explanation:
A line with a perpendicular slope with have a slope that is the negative inverse of the reference line. If the reference line is -(2/3), the perpendicular line will have a slope of (3/2).
The line formed by ab: y = (3/2)x + b
We have one given point on line ab with one coordinate known, (3,4), so let's use it to find b:
y = (3/2)x + b
4 = (3/2)*3 + b for (3,4)
4 = (9/2) + b
b = 4 - (9/2)
b = - 0.5
The equation is y = (3/2)x - 0.5
The slope of (3/2) is equal to the Rise/Run of two points on the line: (3,4) and (w,-5):
Rise = (4 - (-5)) = 9
Run = (3 - w)
Slope = 9/(3-w)
(3/2) = 9/(3-w)
(3/2)(3-w) = 9
(9/2) - (3/2)w = 9
9 - 3w = 18
-3w = 9
w = -3
Point b is (-3, -5)
