Four times a number added to 7 times the number equals 44.

1 answer:

8 0

If you're looking for the value of the number, then here's how:
Let's call the number x
4x + 7x = 44
11x = 44
÷ 11
x = 4
So the number you're looking for is 4, if you wanted to know something else then let me know!

Write the recursive formula then determine the next term of 3,10,24,52

Schach [20]

Answer:

f[1] = 3
f[n] = 2·f[n-1] +4
108

Step-by-step explanation:

We observe that first differences of the given numbers are ...

10 -3 = 7

24 -10 = 14

52 -24 = 28

That is, each difference is 2× the previous one. This suggests an exponential relation that has a base of 2.

We notice that doubling a term doesn't give the next term, but gives a value that is 4 less than the next term. So, we can get the next term by doubling the previous one and adding 4.

Then our recursive relation is ...

f[1] = 3 . . . . the first term

f[n] = 2×f[n-1] +4 . . . . double the previous term and add 4

The next term is 2·52 +4 = 108.

Plaese help !!! 5/7m=15

Darina [25.2K]

$\dfrac{5}{7}m = 15$

Multiply both sides by 7/5.

$\dfrac{7}{5} \times \dfrac{5}{7}m = \dfrac{7}{5} \times 15$

$\dfrac{35}{35} m = \dfrac{7 \times 15}{5}$

$\dfrac{35}{35} m = \dfrac{7 \times 3 \times 5}{5}$

$m = \dfrac{7 \times 3}{1}$

$m = 21$

A wire 22 cm long has a mass of 374 g. What is the mass of 13 cm of this wire?

taurus [48]

Answer:

221 g

The up pinned pic is of inverse variation typed answer.. If u want word problem type answer here are the steps (EVEN IF THE STEPS ARE DIFFERENT ANSWERS REMAIN SAME)

Step-by-step explanation:

Mass of wire from 22cm = 374g

Mass of wire from 1 cm = 374÷22 = 17g

Mass of wire from 13 cm = 13×17 = 221 g
