Answer:

Exact form is [tex]x=-\frac{2}{65}[/tex]

And the decimal form is x  =  −0.0307692

Answer:

The value of x is -2/65

Step-by-step explanation:

The given equation is

8 - 65x = 10

We are asked to find the value of x.

Step 1: Subtract 8 from both sides

-8 + 8 - 65x = 10 - 8

-65x = 2

Step 2: Divide both sides by -65

-65x/-65 = 2/-65

x = -2/65

Therefore, the value of x is -2/65

Answer:

B. 85*

Step-by-step explanation:

1. Understand that a triangle always has the additive degrees of 180.

2. Use x+55+40=180, to isolate x, subtract 55 and 40 from 180.

3. You get x = 85.

Answer:

B. 85 degrees

Step-by-step explanation:

According to the Triangle Sum Theorem, all the angles inside a triangle equal 180 degrees. The work is below:

180-40-55=85. The angle missing is 85 degrees.

Answer:

13 and 27

Step-by-step explanation:

x+y=40

x- smaller

2y-x=41

x=2y-41

Now to plug it into our first equation:

3y-41=40

3y=81

y=27

x=13

Answer:

Tan r = z/y

Step-by-step explanation:

Tangent = opposite / adjacent

Line XY, which is z, is opposite of angle r.

Line XZ, which is y, is adjacent to angle r.

The equation would be Tan r = z/y.

Answer: No, you can't find the tangent ratio of angle rº because the tangent ratio applies to any right triangle, and it applies to right triangles ONLY.

Answer:

38 and 39

Step-by-step explanation:

Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:

x+(x+1)=77

2x+1=77

2x=76

x=38

x+1=39

Hope this helps!

Answer:I believe it is 39 and 38

Step-by-step explanation:

x + (x+1) = 77

2x = 76

x = 38 (1st number)

x+1 = 39 (2nd number)

Answer:

Applying the binomial theorem

[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]

Here we have x = -[tex]\sqrt{2}[/tex], n = 8,

=> 4th term (k = 3) would be:

[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]

Hope this helps!

Dilation

Step-by-step explanation:

A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.

In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.

The image, ΔADE is now a dilated version of the pre-image ΔABC

Answer:

w = 2.5 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 5 and h = 6, thus

A = 0.5 × 5 × 6 = 15 cm²

Thus the area of the rectangle is 15 cm²

A = lw ( l is the length and w the width )

Here l = 6 and w is to be found

6w = 15 ( divide both sides by 6 )

w = 2.5 cm

Answer:

volume= length ×width×height

2×2.5×4.5

22.5

The volume of a right rectangular prism with sides 2 m , 2.5 m and 4.5 m will be 22.5 m³.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

All the sides of a rectangle are;

2 m , 2.5 m and 4.5 m

Now,

Since, we know that;

Volume of rectangle = Length x Width x Height

Substitute all the values we get;

Volume of right rectangular prism = 2 x 2.5 x 4.5

                                                     = 22.5 m³

Thus, The volume of a right rectangular prism with sides 2 m , 2.5 m and 4.5 m will be 22.5 m³.

Answer:

4a ) Difference ⇒ $ 63.24,

4b ) 4 children

Step-by-step explanation:

4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;

y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,

y = 42.16 + 85.15 ⇒ Combine like terms,

y = 127.31

If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;

y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,

y = 105.4 + 85.15 ⇒ Combine like terms,

y = 190.55

Difference; 190.55 - 127.31 = 63.24,

Solution; Difference ⇒ $ 63.24

4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;

169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,

21.08x = 84.32 ⇒ Divide either side 21.08,

x = 4 children

Solution; 4 children

Answer:

y=7* (0.5)^x

Step-by-step explanation:

We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.

i.e. when x=a and x'=a+2.

then y/y=0.25 where y' is the function after putting x' to the old function.

Answer:

30 ounces of solution A

20 ounces of solution B

Step-by-step explanation:

x ounces of solution A

y ounces of solution B

x + y = 50

0.7x  ounces  of salt in the solution A

0.95y ounces  of salt in the solution B

0.8*50 = 40 ounces of salt  in 50 ounces of 80% solution

0.7x + 0.95y = 40

x + y = 50

0.7x + 0.95y = 40

x= 50 - y

0.7(50 - y) + 0.95y = 40

35 - 0.7y + 0.95y = 40

0.25y = 5

y = 20 ounces of solution B

x = 50 - y = 50 - 20 = 30 ounces of solution A
