Answer:

6

Step-by-step explanation:

7=42 is 7*6

6=30 is 6*5

5=20 is 5*4; it's multiplied by the number below it, so 3 will be 3*2

3 = 6

Step-by-step explanation:

Given: 7 = 42, 6 = 30, 5 = 20

7 <em>(</em><em>x </em><em>6</em><em>)</em> = 42

6 <em>(</em><em>x </em><em>5</em><em>)</em> = 30

5 <em>(</em><em>x </em><em>4</em><em>)</em> = 20

Follow the pattern

4 <em>(</em><em>x </em><em>3</em><em>)</em> = 12

3 <em>(</em><em>x </em><em>2</em><em>)</em> = 6

3 = 6

Which of the following is a non-prime factor of 70? Select one: A. 5 B. 7 C. 10 D. 15
Umnica [9.8K]

Answer:

C. 10

Step-by-step explanation:

by deduction, 5 and 7 are prime numbers and 15 is not a multiple of 70, therefore the answer must be 10 as it is a non-prime number and is a factor of 70 (I.e. 10 and 7)

7 dollars each game and I know that because 10 would be 60 plus 16 which is way over and 5 would be 25 plus 16 which is incorrect 6 would be 30 which adding 16 would be 46. FINALLY ADDING 5 extra which is 7 times which is 35 plus 16 is 51.
Hope this helped

Solve and graph the inequality 4x – 10 &lt; 18.
tiny-mole [99]

9514 1404 393

Answer:

  • The graph has an open circle at 7.
  • The arrow points left.

Step-by-step explanation:

Adding 10 and dividing by 4, we have ...

  4x < 28

  x < 7

The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.

  • The graph has an open circle at 7.
  • The arrow points left.

In a basketball tournament, team A scored 6 more points than 3 times as many points as team B scored. Team C scored 45 more poin
velikii [3]

Answer:

"Team C scored 130 points."

Step-by-step explanation:

Let x represent how many points team B scored.

Team A: 3x + 6

Team B: x

Team C: x + 45

Total: 476 points

476 = (x) + (3x + 6) + (x + 45)

476 = x + 3x + 6 + x + 45

476 = 5x + 51

425 = 5x

x = 85

Team A:

3(85) + 6

= 261 pts

Team B:

= 85 pts

Team C:

(85) + 45

= 130 points
