What's the missing terms 5120, 1280, 320, 80,_, _

1 answer:

6 0

Because 5120 and 1280 are quite large numbers, we can find what is being done in the sequence by looking at 320 and 80, where 320 is being divided by 4. Now that we know that this is process, we can just divide 80 by 4 to get 20, the first missing term, and 20 by 4 to get 5, the second missing term. I hope this helps!

A family of 2 adults and 3 children went out to dinner. The total bill was $42. Each child's dinner cost $4. How much did each a

Yanka [14]

Answer: Each adult’s meal costed $15

Step-by-step explanation:

This situation can be modeled by the following equation:

2a + 3c = 42, where a = the cost of an adult’s meal, and c = the cost of a child’s meal

Since we know from the problem that a child’s meal costs $4, we know c:

2a + 3(4) = 42

At this point, we can just solve the resulting equation for a:

2a + 3(4) = 42

= 2a + 12 = 42 (simplify 3(4))

= 2a = 30 (subtract 12 from both sides)

= a = 15 (divide both sides by 2)

So, the cost of each adult’s meal was $15.

Step-by-step explanation:

$f(x)=\dfrac{x^2-4x+2}{x+7}\\\\f(-1)=\text{put}\ x=-1\ \text{to}\ f(x):\\\\f(-1)=\dfrac{(-1)^2-4(-1)+2}{-1+7}=\dfrac{1+4+2}{6}=\dfrac{7}{6}$
