-2.759= 0.25p
p = -2.759/ 0.25
p = 11.036
Answer:
6x-7
Step-by-step explanation:
Hello,
(5x-2)+(2x+6)=67
==>7x+4=67
==>7x=67-4
==>7x=63
==>x=63/7
==>x=9
|AB|=5x-2=5*9-2=45-2=43 (miles)
Answer:
There are a total of 4 + r + 6 marbles in the bag
The probability of a blue is 
The probability of a red is 
The probability of choosing a blue, replacing it and then a red is
× = [tex]\frac{4r}{100+20r+ r^{2} /[tex]
Step-by-step explanation:
Answer:
area= 1/2*(h*b) h- height, b- base
the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)
so they are equal in length
angles in triangle = 180
so 38+38=76
180-76=104
base=24
divide the triangle in the center
so now triangle 1(left) the base = 12
and triangle 2(right) the base = 12
use trigonometric ratios
in this we need to find the height
which is opposite of 38,
we already have the adjacent =12
so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)
Tan38= (12/h)
multiply by h
h*Tan38=12
h=12/tan38 = 15.35929959
