Answer:
x=t-p
Step-by-step explanation:
just move p to the other side and since it crosses the equals sign so you have to change it from positive to negative
A because two negatives make a positive
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°
Answer:
40
Step-by-step explanation:
Let n represent the integer. Then the increase can be written as ...
n + (-12) = 28
We can add 12 to both sides of this equation:
n + (-12) + (+12) = 28 +12
n + 0 = 40 . . . . . . -12 and 12 total to zero; 28 and 12 total to 40.
n = 40
The integer is 40.
Answer:
Step-by-step explanation:
To the evaluate -5.3+7.9
We get
2.6
Therefore the error
=2.6-2.4
=0.2
