In triangle ABC, the length of side AB is 19 inches and the length of side BC is 28 inches. Which of the following could be the length of side AC?
A.
52 inches
B.
7 inches
C.
42 inches
D.
49 inches
=========================================================
Explanation:
Let's say we have a triangle with sides x,y,z
Also, let's further say we know that x = 19 and y = 28 (from AB and BC respectively).
The third missing side z can't be nailed down to a single number, but we can establish a possible range. That range is
y-x < z < y+x
28-19 < z < 28+19
9 < z < 47
So any number between 9 and 47, excluding both endpoints, will work as a possible side length for the third missing side.
Something like 7 inches is too small, so we rule out choice B. Choice D is ruled out since 49 inches is too big. Same goes for choice A also.
The only thing left is choice C. The 42 is between 9 and 47
In other words, 9 < 42 < 47 is true.
So that's why the third missing side could be 42 inches.
Side note: I'm using a modification of the triangle inequality theorem.

The fourth choice is the correct answer!
What is the value of x and y?
Answer:
x = 5/4
y = 15/16
Step-by-step explanation:
y = 3/4x
5/2 x + 2y = 5
Substitute the first equation into the second equation
5/2x + 2(3/4x) = 5
5/2x + 3/2x = 5
Combine like terms
8/2x = 5
4x = 5
Divide by 4
4x/4 = 5/4
x = 5/4
Now find y
y = 3/4 x = 3/4 ( 5/4) = 15/16

Answer:
109.2-23.6 = 85.6
Step-by-step explanation:
use bodmas
B=bracket
O=of or multiplication
D=division
M=multiplication
A=addition
S=subtraction
so when you are opening a bracket you multipli the number in the bracket with the one outside the bracket
I.E
4×27.3=109.3
4×5.9=23.6
109-23.6=85.6

Hi! Pls help:
What is the expanded form of this number?
902.604
(9×100)+(2×10)+(6×110)+(4×1100)
(9×100)+(2×1)+(6×110)+(4×1100)
(9×100)+(2×1)+(6×110)+(4×11000)
(9×100)+(2×10)+(6×110)+(4×11000)
Answer:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
Step-by-step explanation:
(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400
900 + 20 + 660 + 4400 = 5980
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400
900 + 2 + 660 + 4400 = 5962
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562
(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000
900 + 20 + 660 + 44000 = 45580
None of your options work. The answer would be:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
900 + 2 + 0.6 + 0.004
902.604
The solution is: the expanded form of this number 902.604 is:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here, we have,
(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400
900 + 20 + 660 + 4400 = 5980
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400
900 + 2 + 660 + 4400 = 5962
(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562
(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000
900 + 20 + 660 + 44000 = 45580
None of your options work.
The answer would be:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
900 + 2 + 0.6 + 0.004
902.604
Hence, The solution is: the expanded form of this number 902.604 is:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

Describe, in great detail, how you would put a line into slope-intercept form (y = mx + b) if it wasn't already, so that it would be ready to graph.
Use 2y - 4x = 104 as your example.
Answer:
y=2x+52
Step-by-step explanation:
you would put y to one side so subtract 4x from the side with y and move it to 104
2y=104+4x
Now divide by 2 so you have y alone
y=52+2x
answer y=2x+52

Answer:
the value of x n lengh of pq is 12.6
Answer:
12.6
Step-by-step explanation:
They are similar, so their lengths are the same. Except that The second one is bigger, therefore, you need to find the scale in which it is bigger.
7.2 ÷ 4 = 1.8 (line RS ÷ line LM because they are the correlating sides)
3.6 ÷ 2 = 1.8 (line RQ ÷ line LK because they are the correlating sides)
5.4 ÷ 3 = 1.8 (line SP ÷ line MJ because they are the correlating sides)
This tells us the scale is 1.8. So you just multiply 7 by 1.8 to get 12.6
This can be represented as: y = 1.8
7y = x
7(1.8) = x
12.6 = x
