Solve for m 3-2(9+2m)=m

Mathematics
1 answer:
tester [92]3 years ago
7 0

Answer:

m=-3

Step-by-step explanation:

3-2(9+2m)=m

3-2(9)-2(2m)=m

3-18-4m=m

-15-4m=m

-15=m+4m

5m=-15

Divide by 5

5m/5=-15/5

m=-15/5

m=-3

To check if correct, subsitute m for -3 in the equation. And both sides of the equation must be equal

3-2(9+2m)=m

3-2(9+2(-3))=-3

3-2(9-6)=-3

3-2(3)=-3

3-6=-3

-3=-3

Nico was stunned when he opened the mail.Here was a check for $332.50 this is the interest he earned on his investment.One year
Mazyrski [523]

Answer:

Investment A = 3650

Investment B = 1350

Step-by-step explanation:

Given that:

Total interest earned = 332.50

Total Principal invested = 5000

Investment A:

Rate = 8%

Time = 1 year

Principal = a

Interest earned = 0.08a

Investment B:

Rate = 3%

Time = 1 year

Principal = b

Interest earned = 0.03b

a + b = 5000 ____(1)

0.08a + 0.03b = 332.50 - - - (2)

From (1)

a = 5000 - b

Into (2)

0.08(5000 - b) + 0.03b = 332.50

400 - 0.08b + 0.03b = 332.50

400 - 0.05b = 332.50

-0.05b = - 67.5

b = $1350

a = 5000 - b

a = 5000 - 1350

a = $3650

Solve.
jenyasd209 [6]

Answer:

no solution

Step-by-step explanation:

(you do the exact same you'd do in an equation problem. Get x by itself)

3x+1<2x-2<5x+7

1 < -x-2 < 5x+7

3< -x < 5x+9

3 < -6x < 9

-(1/2) > x > -(3/2)

x can't be bigger than -3 halves and be smaller than -1 half, so the answer is no solution

What is the approximate value of q in the equation below?
gayaneshka [121]

<u>Given</u>:

The given equation is q+\log _{2}(6)=2 q+2

We need to determine the approximate value of q.

<u>Value of q:</u>

To determine the value of q, let us solve the equation for q.

Hence, Subtracting \log _{2}(6) on both sides of the equation, we get;

q=2 q+2-\log _{2}(6)

Subtracting both sides of the equation by 2q, we have;

-q=2-\log _{2}(6)

Dividing both sides of the equation by -1, we have;

q=\log _{2}(6)-2

Now, substituting the value of log_2(6)=2.585, we have;

q=2.585-2

Subtracting the values, we get;

q=0.585

Thus, the approximate value of q is 0.585

Hence, Option C is the correct answer.
