5 0

Answer:

Hence, x>0 is the solution of the given inequality.

Step-by-step explanation:

We have to solve the inequality: -3 x-2 x<0

⇒ -5 x<0

now on multiplying both side by -1 we get 5 x>0 ( Since after multiplying by a negative quantity the inequality sign get interchanged)

now on dividing both side of the inequality by 5 we get that x>0.

Hence, x>0 is the solution of the given inequality.

Macy doesn’t have any money in her bank account, but she saves $12.50 each week. Robby has $20 in his bank account, and he saves

denpristay [2]

After 4 weeks, Macy and Robby will have same amount in their accounts.

Step-by-step explanation:

Given,

Amount saved by Macy each week = $12.50

Let,

x be the number of weeks.

M(x) = 12.50x

Amount saved by Robby each week = $7.50

Amount Robby already have = $20

R(x) = 7.50x + 20

For same amount;

M(x) = R(x)

$12.50x=7.50x+20\\12.50x-7.50x=20\\5x=20$

Dividing both sides by 5

$\frac{5x}{5}=\frac{20}{5}\\x=4$

After 4 weeks, Macy and Robby will have same amount in their accounts.

Jason and Kyle both choose a number from 1 to 10 at random. What is the probability that both numbers are odd?

Artemon [7]

Your answer is

B) 1/2

because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.

Glad I could help, and good luck!

2. Out of 35 students participating in a debate, 10 are girls. The probability that winner is a boy is: a)1/7 b)3/7 c)4/7 d)5/7

Gnoma [55]

Answer: d) 5/7

Step-by-step explanation:

10 out of 35 of the students are girls. The number of boys is therefore:

= 35 - 10

= 25 boys

Probability that the winner is a boy is:

= 25/35

Take that fraction to the simplest by dividing both by 5:

= 5/7
