You can substitute “x” For your answer and solve the problem that way ^^
It’s a a way to “check” yourself.
If it doesn’t fit in and you not get the answer shown the x substitute is incorrect.
I personally think they are right! I also have a test on two step/one step equations lol
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?
We can make everything have the same denominator so we can add, subtract, and compare them:
The common denominator between 2, 4, and 8, is 8.
7/8 = 7/8
1/2 = 4/8
1/4 = 2/8
The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:
Laura : 7/8
Daniel: 4/8
Annabelle: 2/8
4/8 + 2/8 = 6/8
So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:
7/8 > 6/8.
This means that Laura rowed more than Daniel and Annabelle.
nope it is not :) although she already explained it

Answer:
The answer is 9.0321.
Answer:
x = -3
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
55+54 + x+74 = 180
Combine like terms
183 +x = 180
Subtract 183 from each side
183-183 +x = 180-183
x = -3
Answer:
-3
Step-by-step explanation:
If x + 74 represents the last angle, then it would be -3 as:
a triangle has 180 degrees
55 + 54 = 109
109 + 74 = 183
183 degrees is 3 over the degrees in a triangle, so you subtract 3 from it to make 180
183 - 3 = 180
idk if that's what its asking for though
