the second of the three is 6 times the first. the third is 6 less than the first. the sum of the second and third numbers is 98. find all three numbers.
Answers
Answer:
83
Step-by-step explanation:
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83
Answer:
first number=14.9,second number=89.4 and third number=8.9
Step-by-step explanation:
let the first number be "a" , second number be "b" and third number be "c"
From the question above we know,
b=6a
c=a-6
And b+c=98
so we can write,
b+c=98
(6a)+(a-6)=98
6a+a=98+6
7a=104
a=104/7
∴a=14.9(correct to 3 sig. fig.)
again
b=6a=6(14.9)= 89.4(correct to 3 sig. fig.)
c=a-6=(14.9)-6=8.9(correct to 3 sig. fig.)
Now if u want to make sure that ur answer is correct just add b+c and see if its 98
b+c=98
89.4+8.9=98.3=98(correct to whole number)

What is 4x-2y=8 in slope intercept form?
Answers
Answer: y = -2x + 4
Step-by-step explanation: In slope-intercept form or y = mx + b form,
the y is isolated or by itself on the left side of the equation.
So start by subtracting 4x from both sides.
That gives us -2y = 4x - 8.
Notice I put the x term first because in y = mx + b form,
the x term comes first on the left side of the equation.
From here, we divide both sides by -2 to get y = -2x + 4.
Y=2x-4
m=2, b= -4

Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his incline skates 32 cm in circumference. How many rotations does each wheel make while Shawn is coasting down the ramp. Round your answer to the nearest rotation.
Answers
Answer:
Step-by-step explanation:
16 rotations
500/32 = 15.625
15.625 rounded = 16
Therefore, the answer is 16 rotations.
Why:
500 and 32 are both given to you in distance. By divided 500 by 32 will give you how many times the shorter distance can fit into the longer distance. This will then give you the amount of rotations in the greater distance.
Once you have the answer, it asks for you to round to the nearest rotation. 15.625 rounds to 16 because 6 is in the tenths place. And we all know a number 5 or greater rounds up. So, 16 is the correct answer.
Answer:
It should be 16 rotations

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9
She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference? (10 points)
Yes, because the mean is larger in the art book
No, because the mean is larger in the art book
Yes, because there is a lot of variability in the art book data
No, because there is a lot of variability in the art book data

Answers
Answer:
The independent variable on the x-axis is the price of a t-shirt and the dependent variable on the y-axis is the number of t-shirts sold.
Step-by-step explanation:
To understand this question, it is crucial to understand what independent and dependent variables are. The independent variable is the one that is manipulated in an experiment. On the other hand, the dependent variable is the one that changes because of a change in the independent variable.
In this problem, the independent variable is the price of a t-shirt. Sera is able to change the price of her t-shirts at will, and changing it will impact the number of t-shirts sold. So, the dependent variable is the number of shirts sold. Sera has no direct control over this variable. She hopes that she will be able to control it by changing the cost of the t-shirts she sells.
Therefore, the independent variable is the price of a t-shirt and the dependent variable is the number of t-shirts sold.
