Step-by-step explanation:
To subtract, you must first:
Find like denominators.
- Note: What you do to the denominator, you must do to the numerator.
- If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.
Simplify:
-----------------------------------------------------------------------------------------
Take for example, a question such as:
7 3/10 - 9/20
First, change the mixed fraction into improper fraction:
7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10
Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:
(73/10)(2/2) = (146/20)
Simplify. Combine like terms
146/20 - 9/20 = 137/20
Simplify.
137/20 = 6 17/20
6 17/20 would be your answer for the example question.

C. 3
Step-by-step explanation:
Formula for slope is given as
The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).
Let,
Plug the values into the formula:
The answer is 6 :))))))))
Answer:
to get the area of a circle, you do pie times radius squaared, so we divide 4 to get the radius. so 2*2 is the radius squared,so now we just times 4 by 3.14= 12.56
so the area= 12.56 inches!
Step-by-step explanation:
Answer:
h=7.65
Step-by-step explanation:
H is directly proportional to the square root of p;
Let k be the constant of proportionality;
Means h=k√p
This means for corresponding points of h and p such that (h1,p1) and (h2,p2) we have;
h1/√p1=h2/√p2
Let h= 5.4 when p = 1.44 and h when p =2.89 be respectively (h1,p1) and (h2,p2)
So that
5.4/√1.44=h/√2.89
5.4/√1.44 ×√2.89 = h
7.65= h
h=7.65
