4x-9=2x+5..solve for X..Help?

Answers

Answer:

x = 7

Step-by-step explanation:

4x - 9 = 2x +5        add 9 from both sides

4x = 2x +14            subtract 2x from both sides

2x = 14.                   divide both sides by 2

x = 7

Answer:

x = 7

Step-by-step explanation:

Rewrite equation

4x - 9 = 2x + 5

Add 9 on both sides

4x -9 +9 = 2x + 5 + 9

Simplify

4x = 2x + 14

Subtract 2x on both sides

4x - 2x = 2x + 14 - 2x

2x = 14

Finally divide both sides by 2

2x/2 = 14/2

x = 7

Hope this helps :)

What is the approximate area of the sector?

Plss helpppp I need it now

Answers

The formula is
SA=x/360 multiplied by pi multiplied by the squared radius
So therefore you substitute the values you have into the equation so:
SA= 300/360 x pi x 13 squared (radius is half of diameter so half of 26 is 13)
Therefore the answer should be
442.440

Step-by-step explanation:

since hypotunees has no value it cancels.

aso it leaves with an adjacent and oppisite

using trig function you will get

tan(x)=(9/4)

inverse tan to get x on its own

(x)=tan^-1(9/4)

What do I do plz help

Answers

Answer:

x = 54°

Step-by-step explanation:

90° = 2x-18°

90° + 18° = 2x

108° = 2x

x = 54°

Answer:

x = 54

Step-by-step explanation:

The two angles added together equal 90 degrees because they are  complementary angles.

x - 18 + x = 90

Combine like terms

2x - 18 = 90

add 18 to both sides

2x = 108

Divide each side by 2

x = 54

Fill in for x

54 - 18 + 54 = 90

36 + 54 = 90

90 = 90

This proves that the answer is true.

Answer:

Step-by-step explanation:

If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.

The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.

There are 99 times and 1 quarter.

A function C(x) = 8x + 15 represents the cost C. in dollars of producing x, T-shirts for
the marching band.

what would be the cost of producing 60 t shirts?
find the number of t shirts if c(x)=303

Answers

Answer:

The cost of producing 60 t-shirts is $495.

36 t-shirts will let the cost, C(x) = 303

Step-by-step explanation:

If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.

C(x) = 8x + 15

C(x) = 8(60) + 15

C(x) = 480 + 15

C(x) = 495

If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).

C(x) = 8x + 15

303 = 8x + 15

288 = 8x

x = 36
