The sum of two numbers is 80 If four times the smaller number is subtracted from the larger number, the result is 10. Find the t

timama [110]

This can be solved using a system of equations.
$\left \{ {{x+y=80} \atop {x-4y=10} \right. 
$
Subtract y from both sides.
$x=80-y$
Substitute:
$80-y-4y=80-5y=10$
Subtract 80 from both sides:
$5y=70$
Divide both sides by 5:
$y= \frac{70}{5} =14$
Substitute.
$x=80-14=66$

Mark this question "True" if the argument is VALID, and "False" if the argument is INVALID: If this number is larger than 6, the

sleet_krkn [62]

This argument is no valid although the first part of the statement is valid. If a number is larger than 6 than its square must be larger than 36. But if the number is smaller than 6, its square does not need to be smaller than 36. For example...

(-100)²=10000

-100 is smaller than 6 but its square is bigger.

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.

Alex17521 [72]

Answer:

The Probability of not getting two consecutive reds is 0.9506

Step-by-step explanation:

Number of sections = 9

Number of red sections = 2

Number of blue sections = 3

Number of green sections = 4

Probability of getting two consecutive reds = $\frac{2}{9} \times \frac{2}{9}=\frac{4}{81}$

So,The Probability of not getting two consecutive reds = $1- \frac{4}{81}=\frac{77}{81}=0.9506$

Hence The Probability of not getting two consecutive reds is 0.9506
