A worker's salary increases by 3.5%. If the raise amounts to $2450, how much was the worker being paid before the raise?

Answer:

x=6

Step-by-step explanation:

13x+12=90

13x=78

x=6

The value of x in the rectangle is 6.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given quadrilateral is a rectangle.

In rectangle each angle has 90 degrees.

So equate 13x+12 and 90 degrees to get x

13x+12=90

Subtract 12 from both sides

13x=90-12

13x=78

Divide both sides by 13

x=6

Hence, the value of x in the rectangle is 6.

In order to find I you would need to isolate it. In order to do this, you divide both sides by w and end up with a/w=l.

Answer:

4c-20= 4

+20  +20

4c= 24

/4 /4

c= 6

Answer:

c = 1 btw can i be brainiest...

Step-by-step explanation:

First, rewrite the left side of the equation and group and combine like terms:

c + (4 − 3c) − 2 = 0

c + 4 − 3c − 2 = 0

−3c + c + 4 − 2 = 0

−3c + 1c + 4 − 2 = 0

(−3 + 1) c + (4 - 2) = 0

−2c + 2 = 0

Next, subtract

2

from each side of the equation to isolate the

c

term while keeping the equation balanced:

−2c + 2 − 2 = 0

−2 − 2c + 0 = −2

−2c = −2

Now, divide each side of the equation by

−2

to solve for

c

while keeping the equation balanced:

−2c - 2 = −2 − 2

−2c − 2 = 1

c = 1

Answer:

A: Not proportional

B: Proportional

Step-by-step explanation:

A: 14/4 = 3.5

40/12 = 0.3333333333333

Therefore A is not proportional

B: 3/9 = 0.3333333333333

15/45 = 0.3333333333333

Therefore B is proportional

Answer:

  6 < x < 23.206

Step-by-step explanation:

The smallest that angle CAD can be is 0°. For that, ...

  2x - 12 = 0

  2x = 12

  x = 6

__

The largest angle CAD can be is the angle that corresponds with triangle CAB being isosceles: CA = AB = AD. Then the length of AC satisfies ...

  AC·sin(48°/2) = 22/2

On the other side, we have ...

  AC·sin((2x-12)/2) = 16/2

This gives us ...

  sin(x -6) = 8/11·sin(24°)

  x = 6 + arcsin(8/11·sin(24°)) ≈ 23.206

__

The range of values for x is ...

  6 < x < 23.206

_____

Additional comment

You may be expected to assume that angle CAD could be as much as 180°. That cannot be the case.

Step-by-step explanation:

Answer:

a = 6, b = - 12

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms to those on the right side.

a(4x - 10) ← distribute parenthesis

= 4ax - 10a

Compare to 24x + 5b , then

4a = 24 ( divide both sides by 4 )

a = 6

Then

5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )

b = - 12
