Answer:

  3) ? = 21

  4) ? = 6

Step-by-step explanation:

3) The given ratio is ...

  A : B = 2 : 7

You want to find ? such that ...

  2 : 7 = 6 : ?

The ratio is equivalent when both numbers are multiplied by the same value.

From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.

__

4) For this one, you need to recognize that the given number corresponds to B.

  A : B = 2 : 3

  2 : 3 = ? : 9

Again, you know that 3×3 = 9, so 3×2 = ? = 6.

Please Help <br> Problem solving
kodGreya [7K]
P  = $1,100
r = 7.25% = 0.0725

A= P(1+r)^t
⇒ 6600 = 1100(1+0.0725)^t
⇒ 6600/1100 = 1.0725^t
⇒ 1.0725^t = 6

Use log to solve it
log(1.0725^t) = log 6
⇒ t * log 1.0725 = log 6
⇒ t * 0.0303973 = 0.7781512
⇒ t = 0.7781512/0.0303973
⇒ t = 25.599 ≈ 25.60 years

Which ordered pair is a solution to the system?
sweet-ann [11.9K]
Answer: C) (-3, -1)
X = -3 and y= -1

If you apply these values in the inequalities
y < 2x + 1
-3 < -2 + 1
-3 < -1
Since -3 is less than -1 , the values hold true for the first equation

y > -x-5
-3 > -1 - 5
-3 > -6
Since -3 is greater than -6, it also holds true for the 2nd equation

Len [333]
Can you please check, if you wrote it down correctly. Cause in this case the answer would be -2= -1. I think that isn’t the solution.
