help me find the answer!! 2-step equation

Answer:

because there are in need of it

Step-by-step explanation:

yes

Step-by-step explanation:

the small and the large triangles are similar triangles.

they have the same angles. and the corresponding sides correlate to each other with the same ratio for every pair of sides.

so,

28 / 82 = (2x + 8) / ((2x + 8) + (5x -4)) =

= (2x + 8) / (7x + 4)

(7x + 4)×28 = (2x + 8)×82

196x + 112 = 164x + 656

32x = 544

x = 17

Step-by-step explanation:

using formula method... insert the variables

Step-by-step explanation:

[tex]90 + 90 + 52 + x = 360 \\ x = 360 - 90 - 90 - 52 \\ x = 128[/tex]

Answer:

x=17

Step-by-step explanation:

1) 4x +7 = 5(x-4)      Congruent angles

2) 4x + 7 = 5x -10    Distributive Property

3) Simplify

4x + 7 = 5x - 10
-4x        -4x
  7 = x - 10
+10       +10

x = 17

Answer:

5

Step-by-step explanation:

Well, there's a formula: to find the measure of any section, you should multiple every section to its ending after the crossing, and then make a proportion.

So, 9(n+7) = 18(n+1)

9n+63 = 18n+18

-9n+45=0

-9n=-45

n=-45/-9

n=5

Hey there!

2(x + y)

DISTRIBUTE 2 WITHIN the PARENTHESES

= 2(x) + 2(y)

= 2x + 2y

Therefore, your answer is: 2x + 2y

Basically, 2 (the first one) is your coefficient, x & y are your variables, and 2 (the second one) is your constant. Whereas, your addition symbol (the sum or +) is your operator.

Good luck on your assignment & enjoy your day!

Answer:

12* y-4

Step-by-step explanation:

The first is twelve. then the asterisk is next. y is for the "number" Lastly, subtract 4.

The line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

Four times the sum of 3.2 and a number is the number less than 1.4

Let the number be n.

It is given that the sum of 3.2 and number,

n + 3.2

Four times the sum, therefore,

4(n+3.2)

The total we got is the number less 1. 4. thus,

4(n+3.2) = n - 1.4

Hence, the line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

Answer:

D. -1/2

Step-by-step explanation:

First to rewrite the equation in numbers

[tex]125=\frac{1}{25}^{y-1}[/tex]

First, we need to find what exponent would get 1/25 to 125.

[tex]\frac{1}{25}^{y}=125[/tex]

Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.

Answer:

Keep it simple: D or -1/2

Answer:

18480 ft

Step-by-step explanation:

Note that 1 mile = 5280 feet. We can use this information to set up a unit converter:

[tex]3.5mi(\frac{5280ft}{1mi})[/tex]

Miles cancels out on the bottom giving us...

[tex]3.5*5280ft=18480ft[/tex]

6x + ( 3x - 9) = 90°( being complementary angles )

6x+3x -9 = 90°

9x = 90° + 9

x = 99 / 9

x = 11

Answer:

Answer:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Step-by-step explanation:

yeah

Answer:

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

Answer:

r = 2

Step-by-step explanation:

Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]

Substitute the known values for their respective variables and solve for the missing coordinate, r.

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\ -\frac{1}{2}=\frac{6-r}{-12-(-4)}\\\\-\frac{1}{2}=\frac{6-r}{-8}\\\\ -8(-\frac{1}{2})=(\frac{6-r}{-8})-8\\\\ 4=6-r\\\\4-6=6-r-6\\\\-2=-r\\\\\frac{-2}{-1}=\frac{-r}{-1}\\\\ 2=r[/tex]

The given function is ,

→ f(x) = -9x + 7 .

And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,

→ f(3) = -9*3 +7

→ f(3) = -27+7

→ f(3) = -20

Hence the required answer is-20 .
