Answer:
Step-by-step explanation:
hello :
2x+7y=1
...(*)
y=4x−8...(**)
(4;8) means x= 4 and y= 8
put this values in (*) and(**) :
2(4)+7(8) =1 62=1 false
8=4(4)-8 8=8 true
so :(4;8) is not solution for this system.
Answer:
h = 9.87 cm
Step-by-step explanation:
Given that,
Base, b = 8 cm
Height = h
Angle, 
We need to find the value of h. We can use trigonometry to find h.
So, the height of the triangle is 9.87 cm.
Answer:
First we need to find 1/3 of 24. When you see "of" replace it with "×".
1/3 of 24 =
1/3 × 24 =
24/ 3 = 8
So 8 stamps are animals. Now we find 3/4 of 8 to find out how many have birds.
3/4 of 8 =
3/4 × 8 =
24/4 = 6
6 have birds
Step-by-step explanation:
24/3 = 8 stamps with pictures of animals, 8 x 3/4 = 6 stamps with birds on them. If it helps 8 has a denominator of 1 so you just multiply the top and the bottom of the fractions. 8x3=24 and you divide that by 4x1

The set of numbers that 3.1214122144 belongs to is called the Irrational numbers. We know this because this number it is not an integer, since it has a fractional part and also is not a whole number. Rational numbers can be decimals but they are terminating decimals. This number is irrational because <span>is a non ending decimal number.</span>
