Answer:
5.8/8=0.725
Rounded number: 0.7
Step-by-step explanation:
Estimate 6/8=0.75
6 because 5.8 rounded to a whole number=6
First, we have to get the variable to one side of the equation, which can be done with simple subtraction.
4x -3 (-6x) = 6x + 9 (-6x)
-2x -3 = 9
now just solve as a regular equation:
-2x - 3 = 9
-2x = 12
x = -6
so, x is equal to -6
Let, number of spiders = x
number of insects = y
6x + 8y = 36
remember, legs can't be in fraction or decimal.
So, only (3, 2) fits with that.
So, there are 3 spiders & 2 insects in his collection.
Hope this helps!
Answer:
x = 12.6
Step-by-step explanation:
Sum of measure of all the arcs of a circle = 360°
m(arc CD) + m(arc CED) = 360°
Since, m(arc CED) = (20x)°
And m(arc CD) = (8x + 6)°
By substituting these measures in teh expression,
(20x)° + (8x + 6)° = 360°
(20x + 8x) + 6 = 360
28x = 360 - 6
28x = 354
x =
x = 12.64
x = 12.6
