Answer:
40 bats sold for $42
26 bats sold for $30
Step-by-step explanation:
x + y = 66
42x + 30y = 2460
solve first equation for y and plug in for y in second equation
42x + 30 (66 - x) = 2460
x = 40
y = 66- 40 = 26
Answer:
w<10

Answer:
(a-z)/z = m
Step-by-step explanation:
a = zm+z
Subtract z from each side
a-z = mz+z-z
a-z = mz
Divide by z
(a-z) /z = mz/z
(a-z)/z = m

Answer:
11y-2x= -90
Step-by-step explanation:
for the point (1,-8)
x=1 and y= -8
for the equation,
2x -4y= -11
x= -1/m
m= -1/x
x = -1/ (-11/2 )
m= 2/11
so for the equation,
y-y1= m(x- x1)
y- -8=2/11(x-1)
11(y+8)= 2(x-1)
11y +88= 2x-2
11y-2x= -90
