Answer:
Step-by-step explanation:
Answer:
(2)/(3) =( 4)/( 3+x)
Cross multiply
2*(3+x)= 4*3
Solve bracket
6+2x=12
Subtract 6 from both sides
2x=6
Divide both sides by 2
x=3
Hope it helps :-)
Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
Answer:
No solutions! :)
Step-by-step explanation:
To find the number of solutions in a problem we must solve it.
x+2x+7=3x-7
Firstly, combine common terms:
3x+7=3x-7
We can subtract 3x from both sides:
7=-7
The solution is 7=-7, which is no solution.
When a number is equal to a number in a solution, it has no solutions!

Answer:
Sorry, it's actually the third one, 4.8 feet
Step-by-step explanation:
First, you divide the length of the family room tv by the length of the tv in Louise's room
5 divided by 1.5 equals 3.33
Then, you divide the width of the family room tv to get the width of Louise's tv
3 divided by 3.33 is 0.9
Now, you follow the formula for perimeter.
(0.9 + 1.5) x 2 = 4.8
The perimeter of Louise's tv is 4.8 feet.
