A survey of eating habits showed that approximately

Response:

j = 21 and n = 14

Step-by-step breakdown:

We start with the equations:

6j + n/3 = 134

j/3 + n = 31

54j + 3n = 1206

j + 3n = 93

53j = 1113

j = 21

(21)/3 + n = 31

7 + n = 31

n = 14

Answer: she needs to finish 4 levels to have a point total less than 20

Step-by-step explanation:

Considering the following:

Initial score = 100 points

Losing points for passing a level = - 8 points

Losing points for catching a flower = - 3 points

Assume Tina catches 6 flowers during each level

Total levels required to have less than 20 points

Points lost per level:

Catching 6 flowers = -(6 × 3)

Passing the level = - 8

= - 18 + - 8 = - 26 points

Levels to finish to achieve less than 20 points

Let the number of levels be y

Starting points - (26 × number of levels) < 20

100 - (26y) < 20

100 - 26y < 20

-26y < 20 - 100

-26y < - 80

y > 80/26

y > 3.07

Therefore, she must finish 4 levels to have fewer than 20 points

Answer:

4.1

Step-by-step explanation:

1.8 multiplied by 0.5 equals 0.9

0.5 multiplied by 0.5 gives 0.25

Calculating 2 times (0.9 plus 0.9 plus 0.25) results in 2 times (1.8 plus 0.25), which is 2 times 2.05

Multiplying 2 by 2.05 results in 4.1

Thus, the result is 4.1
