Answer: 1. 2 2. 4 3. 9
Step-by-step explanation: Hi there!
First, we need to set up our equation by combining like terms.
x+2x+4x+1=15
7x+1=15
Then subtract 1 on both sides
7x=14
Then divide by 7
x=2
So x=2
Put that into all of the x values on the piece of steel to get 2, 4, 9.
Hope this answer helps you!

Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know that the hypotenuse squared is equal to the sum of its squared sides.
h^2=x^2+y^2
Here y=25 and x=8 so
h^2=25^2+8^2
h^2=625+64
h^2=689
h=26.25 ft
They obviously rounded to nearest whole foot.
So Carrie is correct in saying the ladder should be 26 feet.
Answer:
mode is the most occuring number which is in this case 11
you get the median by putting them in order from least to greatest and them marking them out until you get to the middle but if there are two numbers in the middle you add them and then divide by two and that is your median but in this case your median is 11
you get the mean by adding all the numbers together and dividing by how many numbers there are so in this case you are dividing by 9 and when you add oall of these numbers together you get 98 and 98/9 is 10.8888888889 which you would round and get 10.9
hope this helps
