Answer:

x = -10

Step-by-step explanation:

x/2 = -5

Multiply each side by 2

x/2 * 2 = -5 *2

x = -10

Answer: x = 23

∠DBC = 23°

∠ABC = 157°

Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.

180 - 19 = 161

23 × 6 = 138

138 + 23 = 161

If x = 23°, then ∠DBC is 23°.

For ∠ABC, (6(x) + 19°

6(23) + 19°

6 × 23 = 138

138 + 19 = 157

∠ABC = 157°

Answer:

36+24i

Step-by-step explanation:

Given :

A = 25000

P = 20000

r % = 9.6 % = 0.096

n = 12

To Find :

The time taken say t.

Solution :

We know, compound interest is given by :

[tex]A=P(1+\dfrac{r}{n})^{n.t}[/tex]

Taking log both sides :

[tex]A=P(1+\dfrac{r}{n})^{n.t}\\\\log\ \dfrac{A}{P}= n.t\times log( 1+\dfrac{r}{n})\\\\t =\dfrac{1}{n}\times \dfrac{log\ \dfrac{A}{P}}{log(1+\dfrac{r}{n})}\\\\\\t=\dfrac{1}{12}\times \dfrac{log\ \dfrac{25000}{20000}}{log(1+\dfrac{0.096}{12})}\\\\\\t=2.33\ years[/tex]

Hence, this is the required solution.

Answer:

see below

Step-by-step explanation:

1/2 = q + 2/3

Subtract 2/3 from each side

1/2 -2/3 = q+2/3-2/3

Getting a common denominator of 6

3/6 - 4/6 = q

-1/6 =q

p - 3 1/6 = -18.73

Add 3 1/6 to each side

p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6

p = -18 73/100 + 19/6

Get a common denominator

p =- 5619/300 + 950/300

  = -4669/300

=-15 169/300

Answer:

3000

Step-by-step explanation:

If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).

Answer:

x =  9(a+g)

Step-by-step explanation:

x/9 - g = a

Add g to each side

x/9 - g+g = a+g

x/9 = a+g

Multiply each side by 9

x/9 * 9 = 9(a+g)

x =  9(a+g)

Answer and Step-by-step explanation:

The equation would be y = 5x + 75

Now, plug in 1, 2, 6, and 12 for x (which represents the hours) and solve for y (which represents the price).

1 hour - $80

2 hours - $85

6 hours - $105

12 hours - $135

Answer:

y = -5

Step-by-step explanation:

Step 1: Translate

"Sum" is addition

"a number y" is y

"-3" is -3

"is -8" means equal to -8

Step 2: Set up equation

y + -3 = -8

Step 3: Solve for y

Answer:

x = 15

Step-by-step explanation:

subtract 10 from both sides: x/3 = 5

multiply both sides by 3: x = 15

Answer:

x=15

Step-by-step explanation:

[tex]\frac{x}{3} +10=15\\\frac{x}{3}=5\\x=15[/tex]

Step-by-step explanation:

the absolute value of a negative number is positive because the absolute value of a number is the distance from 0 on the number line, and distance is positive. -1 is negative, and positive numbers are larger than negative numbers, so |-5/8| is automatically larger.

Step-by-step explanation:

Answer:100

Step-by-step explanation:

Expand

x = 150 - 0.5x

Add 0.5x to both sides

x + 0.5x = 150

Simplify x + 0.5x to 1.5x

1.5x = 150

Divide both sides by 1.5

x = 150/1.5

Simplify 150/1.5 to 100

x = 100

Answer:

13

Step-by-step explanation:

I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now

The system of the equation is :

[tex]2x=y\\3y-4x=10[/tex]

Thus, the age of the ava's turtle is 5 years.

Given:

Ava's turtle is half as old as her parrot.

The turtle will be 3/4 as old as her parrot in 10 years.

Let us assume the age of the turtle is x years and the age of the parrot is y years.

According to the first statement, the variables can be related as:

[tex]{x}=\dfrac{y}{2}\\2x=y[/tex]

According to the second statement, the variables can be related as:

[tex]\begin{aligned}x+10&=\dfrac{3}{4}(y+10)\\4(x+10)&=3(y+10)\\4x+40&=3y+30\\4x-3y&=-10\\3y-4x&=10\end{aligned}[/tex]

Thus, the system of the equation is :

[tex]2x=y\\3y-4x=10[/tex]

By solving the above system of the equation, we get x=5 and y=10.

Thus, the age of the ava's turtle is 5 years.
