Answer:
y=6nx-10
y+10=6nx
y+10/6x=n
therefore, n=y+10/6x.
Step-by-step explanation:
TURKEY 0.15xy+20y
GOBBLE 0.20xy+0y
x is the number of texts and y is the number of months
400 texts will need to be sent each month because solving the equation 0.15xy+20y=0.20xy+0y
0.15xy+20y=0.20xy
-0.05xy+20y=0
-0.05xy=-20y
turn -0.05xy into (-y/20)x
(-y/20)x=-20y
((-y/20)x=-20y)/-y/20
x=-20y/-y/20
x=400
TURKEY plan because 0.15(500)y+20y is 95y and 0.20(500)y+0y is 100y, meaning TURKEY would be cheaper.
As we know
area of triangle = 1/2 *height*base
32=1/2*8*base
32=4*base
8 =base
9/2, 18/4, 27/6 you just make a equivalent fraction then multiply the whole number by the denominator and add the numerator
