Answer:

x=45/75

Step-by-step explanation:

(1+2/3)/x= 2+7/9

5/3x=25/9

5*9= 3x*25

45=75x

x= 45/75 orx=0.6

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the smallest side is 3 and that the 2nd side is twice the smallest side. This means that the second side will be:

= 3 × 2 = 6

The 3rd side is 6 more than the 2nd side. The 3rd side will be:

= 6 + 6 = 12

The perimeter of a triangle is the addition of its sides. Therefore, the perimeter is:

= 3 + 6 + 12

= 21

The sides are:

1st side = 3

2nd side = 6

3rd side = 12.

Answer: ok the answer is 42

Step-by-step explanation: so q = 17 right? and 25 = Y

so i think you add then you get 42...right? i might not get the right answer

The temperature drops when the temperature goes down from 23°C to -16°C is 39°C.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

The temperature dropped from 23°C to -16°C.

Then the drop in temperature will be

Temperature drop = 23 - (-16)

Temperature drop = 23 + 16

Temperature drop = 39 °C

Answer: 6.5%

Step-by-step explanation:

In 6 years the interest earned is:

= 2,780 - 2,000

= $780

The account earns simple interest which means that it increased by the same rate yearly. Yearly increase is:

= 780/6

= $130

Simple interest rate = Interest payment/ Deposit

= 130/2,000

= 6.5%

Answer:

-13.9 represents the slope

It is the number of units of the product left in stock per week

The negative value shows it decreases per week

Step-by-step explanation:

Here, we want to state what the value -13.9 represents

Generally, the equation of a straight line can be represented by the equation

y = mx + c

where m is the slope

In this case, -13.9 represents the slope of the model

The slope is calculated by dividing a change in y by a change in x

With respect to the question, the slope here represents number of units of the product left in stock per week

[tex]x = -1[/tex]

Step-by-step explanation:

Equation: [tex]1+10x+13=4[/tex]

Step 1: Balance both parts of the equation.

[tex]1+10x+13=4[/tex]

[tex](10x)+(1+13)=4[/tex]

[tex]10x+14=4[/tex]

[tex]10x+14=4[/tex]

Step 2: Reduce 14 from both parts of the equation.

[tex]10x+14-14=4-14[/tex]

[tex]10x= -10[/tex]

Step 3: Split both sides by 10, because [tex]\mathrn {10x = -10}[/tex].

[tex]\frac{10x}{10} = \frac{-10}{10}[/tex]

[tex]10 / -10 = -1[/tex]

Therefore, x = -1.

Answer:

y = 6

Step-by-step explanation:

6 * y * 4 = 2 * 72

y = 2 * 72/24 = 6

6xy × 4 = 2 × 72

or, 6xy = 2 × 72/4

or, 6xy = 36

or, xy = 6

6 = 3 × 2 × 1

Hence, x = 3 and y = 2

or, x = 2 and y = 3

or, x = 6 and y = 1

or, x = 1 and y = 6

Answer:

They sold 10 videos and 30 CDs

Step-by-step explanation:

So, you need two different equations-

We will use c to represent CDs and v to represent videos

So-

c + v = 40

4c + 6v = 180

Single out a variable in the first equation-

v = 40 - c

Because this is equal to v, insert it where v is in the second equation-

4c + 6(40 - c) = 180

Multiply-

4c + 240 - 6c = 180

Solve-

-2c + 240 = 180

-2c = -60

c = 30

Now that you know c, use first equation to find v-

30 + v = 40

v = 10

So c = 30 and v = 10

Answer:

B

Step-by-step explanation:

Area of Trapezoid

Area = (b1 + b2)*h/2

Area = (9 + 13)*11 /2

Area = (22) * 11/2

Area = 121 sqr. units.

Area of the unshaded triangle

Area = 1/2 b * h

Area = 1/2 9 * 11

area = 49.5

Area of the shaded region

Area = 121 - 49.5

Area = 71.5

Answer:

We conclude that

Step-by-step explanation:

Given

<1 and <2 form a linear pair

m∠1 = 4m∠2

To determine

Find the measure of each of the two angles.

Important Points about linear pair:

As

<1 and <2 form a linear pair

m∠1 = 4m∠2

In other words, angle 1 is 4 times the measure of angle ∠2.

Let the angle ∠1 be = x

As the angle 1 is 4 times the measure of angle ∠2, so

The angle 2 will be = 4x

As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so

[tex]x + 4x = 180[/tex]

[tex]5x = 180[/tex]

divide both sides by 5

[tex]\frac{5x}{5}\:=\:\frac{180}{5}[/tex]

[tex]\:x=36^{\circ }[/tex]

Thus, we conclude that

Answer:

x = 61°

Step-by-step explanation:

Since the lower left angle equals to 90°, the other angle on the right must also equal 90°.  Subtract 29 from 90° to get 61° as your x value and as your final angle answer.

Answer:

61°

Step-by-step explanation:

The dotted angke is a right angle which is 90° so,

We can solve for x using algebra

90+x+29=180

x+119=180

x=180-119

x=61

Step-by-step explanation:

Answer:We have been given that a rectangle has a height to width ratio of 3:4.5.

Let h be height and w be width of rectangle.

We can set our given information in an equation as:

Now we will substitute h=1 in this equation.

We can see that width of rectangle is 1.5 times height of rectangle.

Our one set of dimensions of rectangle will be: height=1 and width=1.5.

We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.

Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.  

Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.

Answer:

[tex]g(x) = {3}^{x - 2} - 7[/tex]

Step-by-step explanation:

As we can see, the graph of transformation of f(x) is translated to the right and down.

then, g(x) = f(x - a) - b, where a & b > 0.

from the options, there are 4 translated function of f(x).

but on the second option

[tex] {3}^{x + 7} - 2 = {3}^{x - ( - 7)} - 2[/tex]

a < 0, then it's not the answer we need, same as third option that makes only first and fourth left.

from the picture, horizontal asymptote of f(x) is y = 0.

on g(x) horizontal asymptote is y = -b, where -10 < -b < -5.

and from the options that are left, we can see only fourth option that satisfies what we need.

78.93 - 11.84 = 67.09

20% of 78.93 ≈ 15.79

67.09 + 15.79 = 82.88

You're correct!

Answer:

$150,000

Step-by-step explanation:

The first step is to calculate the total number of units

= 2 +1 +2

= 5

If he buys at the rate of $30,000 for one unit then the total money spent on advertising can be calculated as follows

= 30,000 × 5

= 150,000

Hence the promoter spends $150,000 on advertising
