Answer:

3, 18

Step-by-step explanation:

To write an equation or an expression, define the variables.

x is the first number.

6x is the second number since it is 6 times the first.

Add the expressions together to 21 to solve.

x + 6x = 21

7x = 21

x=3

The first number is 3. The second is 6*3 = 18.

Answer:

x<-3 or x>-1

Step by step explanation:

Start with -5x>15. To get x by itself, we have to divide each side by -5. When we do that we get x<-3. (Don't forget to flip the sign when dealing with negative  · and ÷.) Now answer the second equation. x-5>-6 To get x by itself, add 5 to both sides to get x>-1. Now we have x<3 or x>-1.

ddd [48]

Answer:

Step-by-step explanation:

A = P (1 + k)^t

where A is the final amount,

P is the initial amount,

k is the monthly growth rate,

and t is the number of months.

70 = 50 (1 + k)^3

1.4 = (1 + k)^3

∛1.4 = 1 + k

k = -1 + ∛1.4

k = 0.1187

In a basketball skills competition, Corson successfully made 5 of 7 shots and Charleigh made 3 of 5
xxTIMURxx [149]

Answer:

Corson had a better performance at the skills competition.

Step-by-step explanation:

In order to determine which player had a better performance at the skills competition, we need to find the percentage performance of both the players.

Therefore,

Corson's percentage performance

=\frac{5}{7}\times 100= 71.43%

Charleigh's percentage performance

=\frac{3}{5}\times 100= 60%

\because Corson's percentage performance > Charleigh's percentage performance

So, Corson had a better performance at the skills competition.
