Answer:

12.80 divided by 8 = 1.60

1.60 x 32 = 51.20

Step-by-step explanation:

Answer:

8%

Step-by-step explanation:

when solving with percentages, you can “cross multiply”,

we know the fraction would be set up this way:

[tex]\frac{769}{9950}*\frac{x}{100}[/tex]

*there would be an 100 bc a percentage is out of 100*

Now, you have to multiply 769 by 100

[tex]769*100=\\ 76900[/tex]

Then divide by 9950 to get “x”

[tex]79600/9950=\\ 8[/tex]

Answer:

x = 7

Step-by-step explanation:

Given:

∠DEF = 117°

∠DEG = (12x + 1)°

∠GEF = (5x - 3)°

Find:

value of x

Computation:

∠DEF = ∠DEG + ∠GEF

117° = (12x + 1)° + (5x - 3)°

117° = 17 x - 2

x = 7

Answer:

7

Step-by-step explanation:

(12x + 1) + (5x - 3) = 117

17x - 2 = 117  Combine like terms

17x = 119   Add 2 to both sides

x = 7  Divide both sides by 17

Answer:

1/4

Step-by-step explanation:

This is because you want to get x alone, so if you divide -12 on one side you have to do it on the other side, so you get -3/-12 which can be divided by -3 to be simplified to 1/4. Hope this helps!

Answer:

Step-by-step explanation:

-12x = -3

x = 12 : -3

x = 1/4

--------------------

check

-12 * 1/4 = -3

-3 = -3

Answer:

Step-by-step explanation:

1)

x + 5 = 12, subtract 5 from both sides

x = 7

Subtraction property of equality

2)

x + y = 20 and y = 5, substitute 5 into first equation

x + 5 = 20

Substitution property of equality

3)

2x - 3 = 11, interchange the sides of equality

11 = 2x - 3

Symmetric property of equality

Answer:

1. if x + 5 = 12, then x = 7

:Subtraction property of equality

2. If x + y = 20, and y = 5, then x + 5 = 20.

:Substitution property of equality

3. If 2x3 = 11, then 11 = 2x - 3.

:Symmetric property of equality

Answer:

no

Step-by-step explanation:

for two shapes to be equal the respective angles and sides must be congruent. since 34 doesnt equal 36, the two arent congruent

The steps of the solution into order to solve for x in the equation 6(x-5) = 54 are:

Given the expression 6(x-5) = 54

Expand the expression in parenthesis using the distributive law;

6x - 6(5) = 54

6x - 30 = 54

Add 30 to both sides

6x - 30 + 30 = 54 + 30

6x = 84

Divide both sides by 6

6x/6 = 84/6

x = 14

Therefore the steps of the solution into order to solve for x in the equation 6(x-5) = 54 are:

Step-by-step explanation:

3x+2y-1=0

divide everything by 2, to get y.

3x/2=1.5x, -1/2=-0.5.

then separate 1.5x and -0.5 from y (put them on the other side)

there, y=-1.5x+0.5

Write the equation of the line in slope-intercept with a slope of 1 and passing through the (0,-1)

y = x - 1

Write the equation of the line in slope-intercept with a slope of 4 passing through the (-2,1)

y = 4x + 9

Step-by-step explanation:

Write the equation of the line in slope-intercept with a slope of 1 and passing through the (0,-1)

y = mx + b

if slope is 1, m= 1

y = x + b

if passing through (0,-1), then y = -1, x = 0

-1 = (0) + b

b = -1

then

y = x - 1

Write the equation of the line in slope-intercept with a slope of 4 passing through the (-2,1)

y = mx + b

if slope is 4, m= 4

y = 4x + b

if passing through (0,-1), then y = 1, x = -2

1 = 4(-2) + b

b = 9

then

y = 4x + 9

Answer:

Rolls $6, Folded $4

Step-by-step explanation:

Minh: 6r + 2f = 44

Mikayla: 3r + 9f = 54

Multiply Mikayla's x 2:  6r + 18f = 108

Subtract Minh:               6r + 2f = 44

                                    16f = 64

f = 4, Folded paper is $4.

Substitute 4 for f into one of the equations.

6r + 2(4) = 44

6r + 8 = 44

6r = 36

r = 6 Rolled paper is $6
