Write a real world problem for the two step equation 8b+6=38
can someone help me with this ?
What would be the answer to this question and how would you solve it??
It is #24
the slope is the change in Y over the change in x
x = the first numbers 5 & 10
y = the second numbers 8 & 12
10-5 =5
12-8 = 4
so slope = 4/5

Which is the correct label of the parallel lines? parallel lines a and b are shown. points a and b lie on line a while points c and d lie on line
b?
The parallel lines mentioned in the question are correctly labeled as 'AB' for Line a (which involves points A and B) and 'CD' for Line b (which refers to points C and D).
Explanation:In geometry, parallel lines are often labeled with the same letter. In your case, the parallel lines are described as Line a and Line b. Points A and B lie on Line a, and Points C and D lie on Line b. Therefore, to correctly label the lines, 'Line a' is written as 'AB' since points A and B are on this line. Meanwhile, 'Line b' is labeled as 'CD' since points C and D are on that line.
So, in conclusion, the correct labels for the mentioned parallel lines are AB for 'Line a' and CD for 'Line b'.

What is the simplified answer for -2/3+4/3
-2 + 4 = 2
so:
-2/3 + 4/3 = 2/3
The product of the slopes of two non-vertical perpendicular lines is always -1. It is NOT possible for two perpendicular lines to both have a positive slope because the product of two positives is positive. So for the product of the slopes to be -1, one of the slopes must be positive and the other negative.

Find the exact value for cos π 12 applying sum and difference formulas involving π 3 and π 4 .
First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, π/12 can be split into π/3−π/4.
cos(π/3−π/4)
Use the difference formula for cosine to simplify the expression. The formula states that cos(A−B)=cos(A)cos(B)+sin(A)sin(B)
cos(π/3)⋅cos(π/4)+sin(π/3)⋅sin(π/4)
The exact value of cos(π/3) is 12, so:
(12)⋅cos(π/4)+sin(π/3)⋅sin(π/4)
The exact value of cos(π/4) is √22.
(12)⋅(√22)+sin(π/3)⋅sin(π/4)
The exact value of sin(π/3) is √32.
(12)⋅(√22)+(√32)⋅sin(π/4)
The exact value of sin(π/4) is √22.
(12)⋅(√22)+(√32)⋅(√22)
Simplify each term:
√24+√64
Combine the numerators over the common denominator.

A rectangle has an area of 48 cm^2 and a perimeter of 38 cm. what are the dimensions of the rectangle?
We infer from the question that the dimensions of the rectangle, satisfying both the given area of 48 cm² and the given perimeter of 38 cm, are 12 cm x 4 cm.
Explanation:The topic of this question relates to the geometrical concept of rectangles. We know that the area of a rectangle is determined by the formula Area = length * width and the perimeter is given by the formula Perimeter = 2*(length + width). Given that the area is 48 cm² and the perimeter is 38 cm, we can set up the following equations:
Area = length * width = 48Perimeter = 2*(length + width) = 38Since the Perimeter and Area involve both length and width, we use simultaneous equations to solve this. By trial and error or via substitution method, we find that the dimensions satisfying both conditions are: length = 12 cm and width = 4 cm. Therefore, the dimensions of the rectangle are 12 cm x 4 cm.

What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
The first trail he hiked on took him 4.5 miles away from his house.
The second trail he hiked took him 2.4 miles closer to his house.
The third trail took him 1.7 miles further away from his house
Here the expression of the given problem and apply the arithmetic operations,
⇒ 4.5 - 2.4 + 1.7
⇒ 2.1 + 1.7
⇒ 3.8
Hence, Andre is 3.8 miles away from his house after hiking the three trails.

When 5.7 m is divided by 2 s, the quotient is correctly reported as?
To get the correct answer or get the best degree of precision in the results, the answer or the quotient must be reported based on the least amount of decimal points of the given numbers. In this case, the least number of decimal points is zero since we are given the value 2.
So the quotient is:
5.7 / 2 = 3
Answer:
