Answer:

x = 6 2/3

Step-by-step explanation:

10+3(x+2)=36

10+3x+6=36 Solve inside the parenthesis.

16+3x=36 Combine like terms.

-16 -16 Subtract 16 from both sides.

3x/3=20/3 Divide both sides by 3.

x=6 2/3 The answer is x= 6 2/3, or 6.66666666666667

Answer:

x = 6 2/3

Step-by-step explanation:

10 + 3 (x + 2) = 36

Distribute 3 into (x + 2)

10 + 3 x X + 3 x 2 = 36

10 + 3x + 6 = 36

The expression can also be written as

10 + 6 + 3x = 36

16 + 3x = 36

Subtract 16 from both sides

16 - 16 + 3x = 36 - 16

3x = 20

Divide both sides by 3

3x/3 = 20/3

x = 6 2/3

The slope of a line perpendicular to the line whose equation is y = 3x - 4 is

trapecia [35]

Answer:

m = -1/3

Step-by-step explanation:

y = 3x-4

This is in slope intercept form

y = mx+b m is the slope and b is the y intercept

The slope is 3 and the y intercept is -4

We want the slope of a line that is perpendicular

Perpendicular lines have slopes that multiply to -1

Let m be the slope of the line that is perpendicular

3 * m = -1

Divide each side by 3

3m/3 = -1/3

m = -1/3

Which of the following is a solution of the equation -5x + 2 = -13: answers: x=-9, x=75 x=3 x=-3

slamgirl [31]

Answer:

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13

2. -15 + 2 = -13 A positive times a negative will always equal a negative

3. -13 = -13 Whenever you add anything to a negative number, the

number becomes smaller

Ex: -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........

Although the number itself becomes smaller, its value

becomes bigger

Hope this helps.

Use diagrams or the description of equivalent ratios to show thay 2:3,4:6, and 8:12 are equivalent

VikaD [51]

So
lets say we have
a/b=2a/2b
we know that if we invert one and multiply it by the other (divide them), we get 1 because a/a=1 where a=a

so
2/3 and 4/6 are equivelent because if you divide them we get 12/12=1

2/3 and 8/12 are equivilent because if you divide them we get 24/24=1

and sinde 2/3=4/6 and 2/3=8/12, 2/3=4/6=8/12

they are equivlent

Given $dc = 7$, $cb = 8$, $ab = \frac{1}{4}ad$, and $ed = \frac{4}{5}ad$, find $fc$. Express your answer as a decimal.

Pachacha [2.7K]

A ↔ B ↔ C ↔ D ↔ E ↔ F

$\frac{1}{4} AD$ 8 7 $\frac{4}{5} AD$ ???

AB + BC + CD = AD segment addition postulate

$\frac{1}{4} AD$ + 8 + 7 = AD

$\frac{1}{4} AD$ + 15 = AD

AD + 60 = 4AD

60 = 3AD

20 = AD

AB = $\frac{1}{4} AD$ = $\frac{1}{4}(20)$ = 5

DE = $\frac{4}{5}AD$ = $\frac{4}{5}(5)$ = 4

CD + DE + EF = CF segment addition postulate

7 + 4 + EF = CF

11 + EF = CF

Answer: 11 + EF

Note: You did not provide any info about EF. If you have additional information that you did not type in, calculate EF and add it to 11 to find the length of CF.
