5.31x=9.28-6.65
5.31x=2.63
×=2.63/5.31
x=<u>2</u><u>.</u><u>63</u>
5.31
Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D
We solve for the diameters of radius of the given circles by using the equation,
C = πD
or C = 2πr
where D and r are diameter and radius, respectively.
Solving,
C = 34.54 units
D = C/π = 34.54 units / 3.14 = 11 units
r = C / 2π = 34.54 units/2(3.14) = 5.5 units
C = 59.66 units
D = C/π = 59.66 units/3.14 = 19 units
r = D2 = 9.5 units
C = 23.236 units
D = 23.236 units/3.14 = 7.4 units
r = D/2 = 3.7 units
C = 23.376 units
D = 23.376 units / 3.14 = 7.4 units
r = D/2 = 3.7 units
C = 13.188 units
D = 13.188 units/3.14 = 4.2 units
r = D/2 = 2.1 units
Answer:
i believe it is associative property
Step-by-step explanation:
Well to figure out how to round to the tenth, let's figure out where the tenths place is.
Remember that "Tens" is 2 places to the LEFT of a decimal.
However, we are dealing with "Tenths", so we are actually moving 1 place to the RIGHT of a decimal.
So, with our number, we have 44.9598
44.9598
Remember we are looking for the "Tenths" place, so look 1 place to the RIGHT of a decimal.
44.9 is our number.
To determine if we round up or not, the Hundredths place must be 5 or higher to estimate up. If it does not meet the number 5, we stay at our current Tenths place.
The Hundredths place is 2 places to the RIGHT of a decimal.
We now have 44.95
Since our Hundredths place is 5 or higher, we round up our Tenths place by 1.
9 + 1 = 10
44 + 1.0 = 45.0
Your estimation is 45.0
I hope this helps!
