First we need to multiply to make the fractions have equal denominators so we can add/subtract.
math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12
Now we can find the time she spent on history (I assume this is what you are looking for)
Total time-math time<span>-science time=history time</span>
12/12-4/12-3/12
=5/12
Amy spent 5/12 of her time working on history.
Answer:
-1/2
Step-by-step explanation:
We can find the slope if we are given two points
m = (y2-y1)/(x2-x1)
= (4-8)/(4 - -4)
= (4-8)/ (4+4)
= -4/8
= -1/2
Answer:
the angle shown is a straight angle value of which is equal to 180°
3x + 30. 6 = 180
3x = 180 - 30. 6
3x = 149.4
<h3>x = 49.8</h3>
X^2 and 2x^2 are alike.
They both have variables and the same exponent
