The figure of the kite shown in the figure is a quadrilateral because it has four sides. The lengths of each side is expressed as a function of x and y. In order to determine the values of x and y, you make use of the short lines that mark the sides. These are symbols of congruency. If two sides are equal, you mark them both with the same symbol. So for the figure above, side NM = side LM and side KL = side KN. Therefore, we equate them as follows:
NM = LM
2x + 6 = 3x - 1
3x - 2x = 6 +1
x = 7
KL = KN
2y + 5 = y + 10
2y-y = 10 - 5
y = 5
So, we know that the values are x=7 and y=5. We use this to know the actual values of sides KN and NM.
KN = y + 10
KN = 5 + 10
KN = 15
NM = 2x + 6
NM = 2(7) + 6
NM = 20
Since your total for the English book is 5, you make a ratio of
5:150
to make 5 equal 150, you multiply by 30. So if you multiply 3 by 30, you get 90, and 2 by 30 you get 60
60+90=150
new ratio- 90:60
or 90 pages of literature and 60 pages of grammar
It says that you need to divide 2 exponents with the same base, you keep the base and subtract the powers, its kind of like reducing fractions! :)
Answer:
b
Step-by-step explanation:
Answer:
v = 
Step-by-step explanation:
Given
t = 
( multiply both sides by 4 to clear the fraction )
4t = 3v + 1 ( subtract 1 from both sides )
4t - 1 = 3v ( divide both sides by 3 )
= v
