find the value of 6y - 1 given that 17y - 8 = 9
Answer:
5
Step-by-step explanation:
if 17y-8=9, then you could say that 17y=17, by adding 8 to both sides.
So, y=1
Then, plug that value into the new equation 6y-1.
You recieve 6(1)-1
Therefore, the value of the new equation is 5

The areas of the systems formed by rectangles are listed below:
Case T: A = 88 cm²
Case M: A = 72 cm² + 6 · x cm², where x is a non-negative real number.
Case 1: A = 132 cm² (Correct choice: B)
Case 2: A = 250 m² (Correct choice: C)
Case 3: A = 36 m² (Correct choice: A)
How to determine the areas of rectangles
In this problem we need to determine the area of rectangles and combinations of rectangles, whose formula is shown below:
A = ∑ (b · h)
Where:
A - Areab - Base of the n-th rectangle.h - Height of the n-th rectangle.Now we proceed on each case:
Case T
A = (4 cm)² + (12 cm) · (6 cm)
A = 16 cm² + 72 cm²
A = 88 cm²
Case M
A = (18 cm) · (4 cm) + (6 cm) · (x cm)
A = 72 cm² + 6 · x cm²
Case 1
A = (6 cm)² + (12 cm) · (8 cm)
A = 36 cm² + 96 cm²
A = 132 cm² (Correct choice: B)
Case 2
A = (15 m)² + (5 m)²
A = 250 m² (Correct choice: C)
Case 3
A = (3 m) · (12 m)
A = 36 m² (Correct choice: A)

There are 26 boys and 20 girls in a class.
The boys and the girls have some counters.
The mean number of counters that the boys have is 28.
The mean number of counters that the girls have is 19.
Work out the mean number of counters the 46 children have.
Computing the total number of counters in the class as 1,108, the mean number of counters that the 46 children have is 24.
What is the mean?The mean refers to the average value.
The average is the quotient of the total value divided by the number of items in the data set.
The number of boys in the class = 26
The number of girls in the class = 20
The total number of boys and girls in the class = 46
The mean number of counters that the boys have = 28
The total number of counters that the boys have = 728 (28 x 26)
The mean number of counters that the girls have =19
The total number of counters that the girls have = 380 (19 x 20)
The total number of counters that the class has = 1,108 (728 + 380)
The average or mean number of counters in the class = 24 (1,108 ÷ 46)

Question: It takes a boat 2 hours to travel 24 miles downstream and 4 hours to travel 32 miles upstream.
What is the speed of the boat in still water ? The boat travels at ________ miles per hour in still water.
What is the speed of the current of the river? The speed of the current is_____ miles per hour.
Answer: Boat=10mph, Current Speed=2mph
Step-by-step explanation:
Downstream:
2hrs - 24miles => 1hr - 12miles, ie, 12mph
Upstream:
4hrs - 32miles => 1hr - 8 miles, ie, 8mph
Downstream speed is the speed of boat (b) + current speed (c)
Upstream speed is the speed of boat (b) - current speed (c)
So we have a set simultaneous equation:
b + c = 12
b - c = 8
Adding them together, 2b = 20, b = 10.
Replacing the value of b in one equation, 10 + c = 12, c=2.

Substitute n = k + 2 into the formula.

Prove the formula is true for n = k.
Assume that the formula is true for the (k + 1) term.
Therefore , the solution of the given problem of linear equation comes out to be it is true for some n=k, where k represents one of the values for which we want to prove the proposition.
What exactly is a linear equation?The equation y=mx+b serves as the basis for a regression model curve. The slope is B, and the y-intercept is m. Even if y or y were separate components, the foregoing sentence is occasionally referred to as a "mathematical formula combining two variables." Bivariate linear equations only have two variables. Application problems involving linear equations have no known solutions. The formula for a simple set of equations is Y=mx+b.
Here,
given :
=> n = k+2
In such situation, you can still use induction to demonstrate this claim for any numbers n2. (If you want to give it a try, it's a nice workout.) In the base situation, n=2 rather than n=1 would exist.
In order to be clear, I'd want to point out that the logical step does not consist of 'proving the assertion for n=k+1 given it is true for n=k.
The inductive step is to demonstrate that the assertion is true for n=k+1 after assuming that it is true for some n=k, where k represents one of the values for which we want to prove the proposition.

Problem #1
budget rent a car rented a basic car at a daily rate of $45.95 plus 40 cents per mile. Another company rents a basic car for $46.95 plus 20 cents per mile. For what mileage is the cost the same.
Define the variables
Let
x -----> number of miles
y -----> the total cost
we have
budget rent a car
y=40x+45.95 ------> equation 1
Another company
y=20x+46.95 -------> equation 2
Solve the system of equations
equate equation 1 and equation 2
40x+45.95=20x+46.95
solve for x
40x-20x=46.95-45.95
20x=1
x=0.05 miles
therefore
the cost is the same for 0.05 milesIf the answer is 5 why isn't 5 an option?

The perimeter of the figure is 58 m.
To find the perimeter of the given figure we can divide the figure in three rectangles.
Rectangle 1:
Perimeter= 2 (l + w)
= 2(5 + 2)
= 2 x 7
= 14 m
Rectangle 2:
Perimeter= 2 (l + w)
= 2(5 + 1)
= 2 x 6
= 12 m
Rectangle 3:
Perimeter= 2 (l + w)
= 2(14 + 2)
= 2 x 16
= 32 m
So, the perimeter of the figure is
= 14 + 12 + 32
