Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

Answer:

[tex]{\boxed{\tt{c = 2}}}[/tex]

Step-by-step explanation:

Concept :

Here, we will use the below following steps to find a solution using the transposition method:

[tex]\begin{gathered}\end{gathered}[/tex]

Solution :

[tex]\implies{\tt{9c + 6 = 24}}[/tex]

[tex]\implies{\tt{9c = 24 - 6}}[/tex]

[tex]\implies{\tt{9c = 18}}[/tex]

[tex]\implies{\tt{c = \dfrac{18}{9}}}[/tex]

[tex]\implies{\tt{c = \cancel{\dfrac{18}{9}}}}[/tex]

[tex]\implies{\tt{c = 2}}[/tex]

[tex]\star{\underline{\boxed{\tt{\red{c = 2}}}}}[/tex]

Hence, the value of c is 2.

Answer:

X=3.5

Step-by-step explanation:

AD = 4+3 = 7
ED = X
that is the ADE triangle


AB= 4
CB = 2
this is the ABC triangle
because the A angle shares the same triangles
ED /CB = AD/ AB
X/2 = 7/4
by multiplying all of the equation by 2 to get rid of the 2 under the x

X= 7/2 which is 3.5
so X= 3.5

Step-by-step explanation:

ABC and ADE are similar triangles.

that means they have the same angles, and all side lengths of one triangle correlate to the side lengths of the corresponding sides in the other triangle with the same factor.

so, know the factor of one pair of corresponding sides, you know the factor for the other sides too.

therefore, ED (x) relates to BC (2) with the same factor, as AD (4+3) to AB (4).

x/2 = (4+3)/4 = 7/4

x = 2×7/4 = 7/2

Answer:

y=2, x=-1

Step-by-step explanation:

(-1)(6x-7y=-20)

-6x+7y=20

so now you can eliminate one term

6x+5y=4

-6x+7y=20

12y=24

y=2

plug y back into one equation to find x

6x+5(2)=4

6x+10=4

6x=-6

x=-1

Answer: You can't solve for y or x, but you can graph it.

Hope this helps!

Answer:

x=√10 y=√10

Step-by-step explanation:

a^2+b^2=c^2

c=√20

c^2=20

a^2+b^2=x^2+y^2

x=y

x=√10

y=√10

The number of pages read by Laura each day if The book had 85 pages, the same amount every day, and completed the book in just 10 days, is 8.5.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

The book had 85 pages, the same amount every day, and completed the book in just 10 days,

Calculate the number of pages read each day as shown below,

The number of pages read each day = total number of pages / total number of days

The number of pages read each day =85 / 10

The number of pages read each day = 8.5

Thus, The number of pages read each day is 8.5 pages per day.

Answer:

-1/2

Step-by-step explanation:

1. First, let's take two points from the line.

2. Next, to find the slope, we use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] , plug in the values, and simplify.

Therefore, the slope is -1/2.

Answer:

35°

Step-by-step explanation:

1. First, let's find the measure of Angle y. To do this, we should first know that 56 + y + 51 = 180 because they form a line/straight angle.

2. Next, we have to find the measure of Angle X. We know that the sum of all angles in a triangle is 180 degrees, so [tex]x + 73 + 72 = 180[/tex]

Therefore, x = 35°.

Answer:

9/40 of his salary

Step-by-step explanation:

You may want to add the fractions first or subtract one and then the other. I am going to add them first.

(3/8) + (2/5)

(15/40) + (16/40) = (31/40)

1 whole salary (40/40) - (31/40) = (9/40)

Since 9 and 40 have no common factors, the simplified answer is 9/40.

Answer:

42.7 in^3 of the interior space is occupied by blue water

Step-by-step explanation:

1.  Find the volume of the ball.

2. Take 85% of this volume.

Volume of a sphere:  V = (4/3)(pi)(radius)^3

Here this volume is V = (4/3)(3.14)(125 in^3), or 50.24 in^3

85% of this volume is 0.85(50.24 in^3) = 42.7 in^3

42.7 in^3 of the interior space is occupied by blue water.

Answer:

£120

Step-by-step explanation:

If the phone has been discounted by 35%, then it is now 65% of the original price (as 100 - 35 = 65).

Divide the discounted price by 65 to find the amount per 1%, then multiply by 100 to get the original price.

(78 ÷ 65) x 100 = £120

Answer:

It was about $222.86

Step-by-step explanation:

1.) First cross multiply [tex]\frac{78}{x}[/tex] x [tex]\frac{35}{100}[/tex]  (new price over original price) x (percent over 100)

2.) 78 x 100 is 7800 and 35 x (x) is just 35x

3.) 35x=7800; So divide by 35 on both sides

4.) You get X= 222.857143 so about $222.86 was the original price

Answer:

(0, 1)

Step-by-step explanation:

y > 3x - 1

When x = 0:   y > (3 x 0) - 1  ⇒  y > -1

When x = 1:    y > (3 x 1) - 1  ⇒   y > 2

When x = 2:   y > (3 x 2) - 1  ⇒  y > 5

Therefore the only point that satisfies this is (0, 1)
