You can't remove a variable but you can separate the variable from the rest of the equation. If you are adding for example 64+x=88 you would subtract the 64 from 88. You will get the value of x. For anything else, you would do the opposite of whatever you are doing. Multiply if you are dividing, add if you are subtracting and hence forth. I hope this helped.
Answer:
70 degrees, 21 degrees, 37 degrees
Step-by-step explanation:
For the rectangle
- Angle B= 90 degrees<em> (right angle)</em>
Find Angle AED = 180-46-90=44 degrees
All angles add up to 180 so we can find x
66+44=110, therefore Angle x = 180-110=70 degrees
XYZ is equilateral therefore all angles = 60 degrees
This allows us to find angle WZX, 180-60=120
Angle X=180-120-39=21 degrees
PQR is isoceles so the base angels are equal QRP=71 degrees
180-71=109 degrees. 180-109-34=37 degrees = Angle X
Good Luck!!
The temperature which has best degree of precision would
actually be the temperature reading which has similar decimal place with the
error. So the best answer would have 1 decimal and from the choices above, this
would be:
D. 16.0°C
Since t is your variable you have to assign something for it to represent and 12 is your constant so no matter what it's going to stay the same. You could do "john plants trees for a living. He gets $12 for showing up to work, and $65 for every tree he plants"
Answer:
74/15
Step-by-step explanation:
x - 3 =
to remove fractions multiply each side of equation by 40
3/4x(40) - 3 = 7/10(40)
120/4x - 120 = 280/10
simplify:
30x - 120 = 28
add 120 to each side to get:
30x = 148
x = 148/30 or 74/15 simplified
