well, the difference from 5600 to 4200 is 1400.
If we take 5600 to be the 100%, how much is 1400 off of it in percentage?
Step-by-step explanation:
x-int
-7x=28
x=-4
(-4,0)
-4y=28. y-int
y=-7

Answer:
b = 50°
c = 130°
Step-by-step explanation:
Two angles A and B are complementary if:
A + B = 90°
And two angles are supplementary if:
A + B = 180°
Then, we know that:
a = 40°
b is a complement of a (this means that a and b are complementary angles)
c is a supplement of b (this means that b and c are supplementary angles).
From the first statement, we have that:
b + a = 90°
Replacing the value of a we get
b + 40° = 90°
b = 90° - 40° = 50°
b = 50°
And now we can use that b and c are supplementary, then:
b + c = 180°
replacing the value of b we get:
50° + c = 180°
c = 180° - 50° = 130°
c = 130°
Then the values we wanted are:
b = 50°
c = 130°
Answer:
The tree grew 8 and 3/4 inches.
Step-by-step explanation:
To get this answer, first subtract the whole numbers.
21 - 12 = 9
Now do the same with the fractions.
1/8 - 3/8 = -2/8
Now add those two together.
9 - 2/8 = 8 6/8 = 8 3/4
