Answer:
[tex]g(n) = \frac{11}{3} + \frac{5n}{3}[/tex] or g(n) = (11/3) + (5/3)n
Step-by-step explanation:
Equation: [tex]3m - 5n = 11[/tex]
To write a formula for g(n) in terms of n, we have to get m seperately.
[tex]3m - 5n = 11[/tex], add 5n in both sides
[tex]3m - 5n + 5n = 11 + 5n[/tex], now add
[tex]3m = 11 + 5n[/tex], now divide both sides by 3
[tex]\frac{3m}{3} = \frac{11 + 5n}{3}[/tex]
[tex]m = \frac{11}{3} + \frac{5n}{3}[/tex]
Now, replace m with g(n)
[tex]g(n) = m[/tex]
[tex]g(n) = \frac{11}{3} + \frac{5n}{3}[/tex]

Evaluate - 2 + 7+ (-4).
Answer:
1
Step-by-step explanation:
You start by adding -2 and 7.
Because the 2 is negative, it's like subtracting from 7.
This is how you get 5 from -2 +7.
Next, you have to add 5 and -4.
It's like subtracting again, so you get 1.

(7a-1)(x^2+2x-5)
Answer:
7ax2+14ax−x2−35a−2x+5
Step-by-step explanation:
(7a+−1)(x2+2x+−5)
=(7a)(x2)+(7a)(2x)+(7a)(−5)+(−1)(x2)+(−1)(2x)+(−1)(−5)
=7ax2+14ax−35a−x2−2x+5
=7ax2+14ax−x2−35a−2x+5
Answer:
Step-by-step explanation:
(7a - 1) (x² +2x -5) =7a*((x² +2x -5) + (-1)*(x² +2x -5)
= 7a*x² + 7a*2x + 7*(-5) +(-1)*x² +(-1)*2x + -5*-1
= 7ax² + 14ax - 35 - x² -2x + 5
= 7ax² - x² + 14ax - 2x -30
Old McDonald had a farm. In one pen the old farmer had chickens and bulls together. In that pen there were 40 animals in total, but there were 130 legs. Can you figure out how many chickens and bulls are in that pen?
Answer:
There are 15 numbers of chicken and 25 numbers of bulls.
Step-by-step explanation:
The pen had chickens and bulls. The pen contains 40 animals in total. The number of legs in the pen is 130 .
Let
a = number of chicken
b = number of bull
a + b = 40................(i)
A chicken has 2 legs and a bull has 4 legs.
The total legs can be represented as
2a + 4b = 130...........(ii)
combine the equation
a + b = 40................(i)
2a + 4b = 130...........(ii)
a = 40 - b
insert the value of a in equation(ii)
2(40 - b) + 4b = 130
80 - 2b + 4b = 130
80 + 2b = 130
2b = 130 - 80
2b = 50
divide both sides by 2
b = 50/2
b = 25
Insert the value of b in equation (i)
a + b = 40
a + 25 = 40
a = 40 - 25
a = 15
There are 15 numbers of chicken and 25 numbers of bulls.

Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43

What is coordinate system?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements.
Parallel lines are lines in a plane that are always the same distance apart.
The perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees
When the distance between the lines is constant then the lines are called parallel lines.
The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
In the graph, the line k is parallel to the line n and the line n is perpendicular to line n.
k || n and n ⊥ m.
Hence, the correct option is B, k || n and n ⊥ m statement is true regarding the parallel and perpendicular lines in the diagram.

Fernando buys milk to make milkshakes for all his friends. He buys 1 quart of milk and one eighth
gallon of milk. How many cups of milk does he buy? Worth 10 Pts
Answer:
Fernando buys 6 cups of milk to make milkshakes for all his friends
Step-by-step explanation:
Fernando buys 1 quart of milk and one eighth gallon of milk.
1 quart = 4 cups
1 gallon = 16 cups
So, [tex]\frac{1}{8} gallons = \frac{1}{8} \times 16 = 2 cups[/tex]
So, 1 quart of milk and one eighth gallon of milk = 4 cups + 2 cups = 6 cups
So, He buys 1 quart of milk and one eighth gallon of milk i.e. 6 cups
Hence Fernando buys 6 cups of milk to make milkshakes for all his friends

Step-by-step explanation:
what is the volume of this figure ??
Answer:
210 cm³
Step-by-step explanation:
The formula for the volume of a rectangular prism is:
V = lwh
where l is the length, w is the width, and h is the height
Let's substitute the given values into this equation:
V = lwh
V = (5)(6)(7)
Multiply:
V = (5)(6)(7)
V = (30)(7)
V = 210
Therefore, the volume of the prism is 210 cubic centimeters.
the table shows the time 50 students spent on their homework.

0 ≤ t < 30 /7
30 ≤ t < 60 / 27
60 ≤ t < 90 / 12
90 ≤ t < 120 /4
work out an estimate for the mean time the students spent on their home work.
Answer: Mean = 52.8 mins
Step-by-step explanation:
We have lapses of 30 minutes, so we can write the average for each, this means that:
0 < t < 30 can be averaged to the middle of the range: 15 min.
Doing this, we have that:
7 students 15 min
27 students 45 min
12 students 75 min
4 students 105 min.
Now we can calculate the mean:
mean = (x1*n1 + x2*n2 + ...)/N
where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students
Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)
Mean = 52.8 mins

A) How many 4-digit numbers are multiples of BOTH 2 and 5?
B) How many 4-digit numbers are multiples of at least one of these two numbers: 2, 5?
C) How many 4-digit numbers are neither multiples of 2 nor multiples of 5?
Answer:
A) 900
B) 5400
C) 3600
Step-by-step explanation:
A) Number of 4 digit multiples of 5:
(9999-1000+1)/5= 1800
[I added one to the 9999-1000 because it includes 9999]
Now, out of those 1800 numbers that are divisible by 5, 900 of them are even. (so they are divisible by 10 [or 5 and 2])
Therefore, the answer to A is 900
B) Number of 4 digit multiples of 2:
(9999-1000+1)/2= 4500
This means that there are 4500 even 4 digit numbers.
We have already figured out that there are 900 numbers that are divisible by both 5 and 2. 1800-900=900 4-digit numbers that are not divisible by 2, but are divisible by 5.
So if we add the 4500 (numbers that are divisible by 2) and the 900 (numbers that are only divisible by 5, but not 10), we get 5400.
C) There are 9999-1000+1= 9000 4-digit numbers. We know that there are 5400 numbers that are divisible by either 5 or 2, so 9000-5400=3600

Ian needs to replace two concrete sections in his sidewalk, as modeled below. Each section is 36 inches by
36 inches and 4 inches deep. He can mix his own concrete for $3.25 per cubic foot. How much money will it cost Ian to replace the two concrete sections?
Answer: $19.5
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism = width x length x height
Replacing with the values given:
Since 1= 1/12 foot
36 in /12 = 3 foot (length and wifth)
4 in /12 = 1/3 foot (height)
V = 3 x 3 x 1/3 = 3ft3
Next, we multiply it by 2 (since there are 2 sections):
3 x 2 = 6 ft3
Finally we multiply it by the cost of each cubic foot:
6 x 3.25 = $19.5

3. Juanita wants to buy a computer. She needs to earn at least 400 dollars. If she makes 9
dollars an hour and has already saved 40 dollars, how many hours does she need to
work?
Answer:
40 hours
Step-by-step explanation:
9x + 40 = 400 (with x being how many hours she has worked). We get rid of the 40 on both sides by subtraction. Our new equation is 9x = 360. Now we divide 9 on both sides and we learn that x = 40.

what is the sum of 9/16 and 5/16?
Answer:
7/8
Step-by-step explanation:
sum = answer to an addition problem
This means we need to add.
To add fractions with like denominators, simply add the numerators, or the numbers above the fraction sign.
9/15 + 5/16
9 + 5 = 14
numerator = 14
Keep the denominator:
denominator = 16
14/16
Simplify:
(divide the numerator and denominator by 2)
14/2 = 7
16/2 = 8
7/8
Therefore, the sum is 7/8.
The sum of the two fractions shown of 9/16 and 5/16 is 7/8.
When adding fractions, if they have the same denominator, you can simply add up the numerators and keep the denominator.
This means that the sum of 9/16 and 5/16 is:
= (9 + 5) / 16
= 14 / 16
You then need to take this to its simplest form by dividing both the numerator and denominator by their highest common factor which is 2.
= (14 ÷ 2 ) / (16 ÷ 2)
= 7 / 8
In conclusion, the sum of these fractions is 7/8.
