500 x .15 = $75.00.........................
Answer:
x = -13
Step-by-step explanation:
or, (4x-7)/x = (5x+6)/x
or, (4x-7) = (5x +6)
[the x gets cancelled when it comes to opposite side]
or, 4x-5x = 6+7
or, -x = 13
or, x = -13
Solve 5+8 and get 13(3+x) then muliply 13×3 and 13×X... you will end up with 39+13x
A and b are the minutes spent on machine A and machine B, respectively.
a+b = 40
b = 40-a
8a + 6b = 300
8a + 6(40-a) = 300
8a + 240 - 6a = 300
2a = 60
a = 30
b = 40-a = 10
30 minutes on machine A and 10 minutes on machine B
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = 
and tan60° = 
, then
sin60° = 
= 
= ( cross- multiply )
x = 4 ( divide both sides by )
x = 4
and
tan60° = 
= 
= ( multiply both sides by y )
y = 2 ( divide both sides by )
y = 2
