The answerer is combining terms in x with constants
that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms
= 31x + 0.5 ← correct simplification
1 2/5 x 3 4/5 = 5.32 -- with calculator
----------------------------------------------------
You can change mixed fractions to improper fractions.
1 2/5 = 1 x 5 + 2 = 7 = 7/5
3 4/5 = 3 x 5 + 4 = 19 = 19/5
7/5 x 19/5 = 133/25 = 5.32
-----------------------------------------
To make sure you can then turn the improper fractions to decimals.
7/5 = 1.4
19/5 = 3.8
1.4 x 3.8 = 5.32
--------------------------
Whenever I get mixed fraction questions, I always check it in these different excess ways just to make sure :3 Hope it helped..
The values for x and y are respectively given as
This is further explained below.
<h3>What is the values for
x and y ?</h3>
Generally, the equation for secent is mathematically given as
Therefore
80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90

6 weeks is the least and use 46+14x=138
The correct answer is w=8x2 - y
