What is the answer to: 1-x >2x-2

1 answer:

5 0

$1 - x > 2x - 2$
Add x to both sides

$1 > 3x - 2$
Add 2 to both sides

$3 > 3x$
divide by 3 in both sides

$1 > x$
or
$x < 1$

Answer:

A (-1,-6)

Step-by-step explanation:

A system of equations is a set of two or more equations which intersect at a point (x,y). This is the solution. Any system can be solved using graphing, elimination or substitution. To solve this system of equations, use elimination. Line up each variable and subtract the like terms.

2x - 3y = 16

5x - 3y = 13

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

-3x = 3

x = -1

Substitute x = -1

2(-1) - 3y = 16

-2 - 3y = 16

-3y = 18

y = -6

Mashcka [7]

Answer:

68°

Step-by-step explanation:

ABD is a right angle and the measure of it is 90°

m<CBD + m<ABC = m<ABD

4x + 52° + 8x - 10 = 90° add like terms

12x + 42° = 90°

12x = 48°

x = 4

m<CBD is 4x + 52° replace x with 4

4×4 + 52 = 68°

Write an equation of the line that passes through points (4,1) and (-2,7)

jeka94

Answer:

y = - x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (4, 1) and (x₂, y₂ ) = (- 2, 7)

m = $\frac{7-1}{-2=4}$ = $\frac{6}{-6}$ = - 1, hence

y = - x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (4, 1), then

1 = - 4 + c ⇒ c = 1 + 4 = 5

y = - x + 5 ← equation of line

To complete her holiday wrapping Bella needs identical strips of ribbon measuring 3.5 feet each she has 85 feet of ribbon in tot

Anon25 [30]

Answer:

She can cut 24 ribbon from this long strip.

Step-by-step explanation:

Given that,

Bella needs identical strips of ribbon measuring 3.5 feet each.

She has 85 feet of ribbon.

3.5 feet is length of 1 ribbon.

1 feet is length of $\frac{1}{3.5}$ ribbon

85 feet is length of $\frac{1\times 85}{3.5}$ ribbon

≈24.28

$\frac{85}{3.5}=\frac{85\times10}{35}=\frac{85\times2}{7}=\frac{170}{7}$

7) 170(24

_______

______

So, she can cut 24 ribbon from this long strip.
