Answer:
29.3
Step-by-step explanation:
4x+12+5x+3x-4=360
Add the X's up & move the numbers w/out factors (X's) to the 360 side. This will look like 12x=352
Then, you divide each by 12, leaving you with x=29.3
Might be wrong, let me know and I will rework it.
Answer:
your answer could be A
Step-by-step explanation:
Is %
=
of 100
x 6
=
550 100
cross multiply and divide
100x=3300
divide both sides by 100
x=33
Start by representing the lengths of the three sides of your triangle:
first side: x-4 (inches)
second side: x (inches)
third side: (x-4) + 3 (inches)
Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):
x-4 + x + x-4 -3 = 15
3x-11=15
3x=26
x=26/3
Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).
Answer:
y=9x+1.6
Step-by-step explanation:
bring the 10.6 over by adding it to both sides
