Answer:
142 degrees
Step-by-step explanation:
As 38 degree and angle 7 form a linear pair, they are supplementary
Let the measure of angle 7 be x
Hence, x+38=180
x=180-38
x=142 degrees
-3.2=2.5+1.2m
-2.5 -2.5
------
-5.7/1.2= -4.75
m= -4.75
Answer:
Look below
Step-by-step explanation:
To verify that the solution is (3,4) we can plug the numbers back into the equation.
Remember that the solution to a linear equation is represented in the form (x,y). Therefore we plug 3 in for x and 4 in for y.
4=3+1
4=4 Correct!
Now we need to check the second equation
4=-2(3)+10
4=-6+10
4=4 Correct!
Therefore the solution is (3,4)
32% = 0.32
Usually = 400x32/10
Now do 32/100 = .32
Answer is A. 400x0.32
