Answer:

x = 3

Step-by-step explanation:

Combine like terms

18x - 21 = 33

add 21 to both sides

18x = 54

divide both sides by 18

x=3

How do I solve -2m=16m-9

Brums [2.3K]

-2m = 16m - 9

First, take '16m' from both sides.
$-2m - 16m = -9$
Second, add '-2m - 16m' to get '-18m'.
$-18m = -9$
Third, divide both sides by '-18'.
$m = \frac{-9}{-18}$
Fourth, change the fraction into a negative.
$m = \frac{9}{18}$
Fifth, find the GCF of 9 and 18.
The GCF is 9.
Sixth, divide the numerator by the GCF.
$9$ ÷ $9 = 1$
Seventh, divide the denominator by the GCF.
$18$ ÷ $9 = 2$
Eighth, rewrite the fraction in simplest form.
$m = \frac{1}{2}$

Answer as fraction: $m = \frac{1}{2}$
Answer as decimal: $m = 0.5$

alexdok [17]

Answer: Eliza wakes up at 6:25 A.M.

Step-by-step explanation:

What I did is first used the 45 minutes to make the time 10:00 P.M. which leaves you with 8 hours and 25 minutes, then i added the 8 hours onto 10:00 P.M. which leaves you at 6:00 A.M. with 25 minutes left, then you add the 25 minutes onto 6:00 A.M. which puts it at 6:25 A.M.

Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive t

malfutka [58]

Answer:

$P(t)=37\times (4)^{(t/9.1)}$

Explanation:

The number of emails is multiplied by 4 every 9.1 weeks.

Thus, since Tobias initially sent the chain letter to 37 friends, the number of letters will grow as per this geometric series:

Start: 37 letters

In 9.1 weeks: 37 × 4

In 2 × 9.1 weeks: 37 × (4)²

In 3 × 9.1 weeks: 37 × (4)³

As you see, the exponent is the number of weeks divided by 9.1

Thus, if your variable is the number of weeks, t, then the exponent is t/9.1

And the exponential function, P(t) will be:

$P(t)=37\times (4)^{(t/9.1)}$

A right triangle has a hypotenuse C=12cm and a an angle A= 30°. find the length of side a, witch is opposite angle A

Alisiya [41]

Use the sin identity to find that side. Sin(30) = a/12...12 sin(30) = a, and a = 6
