Ron has 22 cards
number one tip in math, try to create equation!
set number of cards Ron has as x (always set x as what you are looking for)
set number of cards Tori has as (x-9) because if Ron has 9 more cards than Tori that's same thing as saying Tori has 9 cards less than Ron
Number of cards Tori and Ron has need to equal 35
Therefore,
x + (x-9) = 35
Solve:
2x-9=35
bring over 9 to other side
2x=44
divide both sides by 2
x=22
So number of cards Ron has is 22
Answer:
a = 70 km/h - 20 km/h / 0.008 h = 50 km/h / 0.008 h = 6250 km/h²
Given the equation 4(3b + 2)² = 64,
dividing both sides of the equation by 4, we have
(3b + 2)² = 16 and getting the square root of both sides,
(3b + 2) = 4 and (3b + 2) = -4
We can solve for b for each equation and have
3b = 2 | 3b = -6
b = 2/3 | b = -2
Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>
Given:
Karen earns $54.60 for working 6 hours.
Amount she earns varies directly with the number of hours she works.
She need to work to earn an additional $260.
To find:
Number of hours she need to work to earn an additional $260.
Solution:
Let the amount of earnings be A and number of hours be t.
According to question,
...(i)
where, k is constant of proportionality.
Karen earns $54.60 for working 6 hours.
Divide both sides by 6.
Put k=9.1 in (i).
Substitute A=260 in the above equation.
Divide both sides by 9.1.
Therefore, she need to work extra about 29 hours to earn an additional $260.
