Answer:
The measure of the two angles are 27° and 153° respectively
Step-by-step explanation:
Given parameters
Let the first angle be represented by x°
And the second angle which is supplementary to the first be represented by y°
From the question, we have that y measures 126° less than x.
So, y = x - 126°
Two angles are said to be supplementary if the both add up to 180.
In this case, it means that x and y are supplementary if and only if x and y add up to 180.
x + y = 180
Substitute x - 126 for y
x + x - 126 = 180
2x - 126 = 180 --- collect like terms
2x = 180 + 126
2x = 306 ----- multiply both sides by ½
2x * ½ = 306 * ½
x = 153°
Recall that y = x - 126°
Substituton 153 for x
y = 153 - 126
y = 27°
Hence, the measure of the two angles are 27° and 153° respectively
Answer:
The equivalent expression to the given expression 4m-2+(-8m) is -2(2m+1)
That is 4m-2+(-8m)=-2(2m+1)
Step-by-step explanation:
The given expression is 4m-2+(-8m)
To find the equivalent expression to the given expression 4m-2+(-8m):
4m-2+(-8m)=4m-2-8m ( here using Associative property )
=-4m-2 ( adding the like terms )
=-2(2m+1) ( taking common term -2 in the above expression )
Therefore 4m-2+(-8m)=-2(2m+1)
Therefore The equivalent expression to the given expression 4m-2+(-8m) is -2(2m+1)
That is 4m-2+(-8m)=-2(2m+1)
Answer:
Percentage of one lap around the track of
the total race = 0.25%
It will take 300 laps to complete 75% of the race.
Step-by-step explanation:
1.2/480=0.0025
0.0025*100=0.25
480/100*75= 360
360/1.2=300
