Answer:
Angle 1 is 57 degrees
Angle 3 is 57 degrees
Angle 4 is 123 degrees
Step-by-step explanation:
Cause a straight line is 180 degrees and if angle 2 is 123 degress then angle 3 is 57 degrees and i got that by Subtracting 180-123 =57
Then for angles one you do the same maththat you do for finding angle 3
Then for angles 4 subtract 180-57=123
Answer:
x = 10
Step-by-step explanation:
Given
- (x - 3) = - 7 ( divide both sides by - 1 )
x - 3 = 7 ( add 3 to both sides )
x = 10
The problem given above is simply a conversion problem. <span>We
are asked to convert from units of acres to units hectares. To do
this, we need a conversion factor which would relate the different units
involved. We either multiply or divide this certain value to the original
measurement depending on what is asked. For this case, we use the given values to determine the relation. We do as follows:
1 hectare = 100 m x 100 m = 10000 m^2
1 hectare = 10000 m^2 ( 1 ft / 0.3048 m )^2 = 107639.10 ft^2
107639.10 ft^2 ( 1 acre / 43600 ft^2 ) = 2.47 acre
Thus, 1 hectare = 2.47 acres
12.0 acres ( 1 hectare / 2.47 acres ) = 4.86 hectares

Step-by-step explanation:
a^2 + 2(b - 6) - 17. a = -7 b = 2
= (-7)^2 - 2(2 - 6) - 17
= 49 - 4 + 12 - 17
= 40
Just calculate this:
A) 2(3m + 5) = 6m + 10 - incorrect
B) -2(5 - 3m) = -10 + 6m - could be correct
C) 2(3m - 10) = 63 - 20 - incorrect
So <u>the correct answer has to be B</u>: -10 + 6m is the same as 6m - 10.
