Answer:

1/7

Step-by-step explanation:

Take your equation: 4-(3x+3)=4x

Then, use the distributive property to carry out the negative sign, so you get 4-3x-3=4x

Add 3x to both sides to get: 4-3=4x+3x

Add like terms together to get: 1=7x

Flip the sides to get: 7x=1

Divide by 7 on both sides to get 7x/7=1/7

Simplify to get: x=1/7

Answer:

4-(3x+3)=4x

4-3x-3=4x

4-3=4x+3x

1=7x

x=1/7

4-(3x+3)=4x

4-3x-3=4x

-3x-4x=-4+3

-7x=-1

x=-1/-7

-/-=+

so -1/-7 it equal to 1/7

you dont want negative x

x=1/7

Can some people answer this for Me please

Alik [6]

Equal to 1, and you'll just add a 4 and that will make it 4/4 and like both are the same numbers it will become 1 whole

Determinet the x-intercept for 3x+2y=14

DerKrebs [107]

The x-intercept is for y = 0.

Put y = 0 to the equation of a line 3x + 2y = 14

$3x+2(0)=14\\\\3x=14\qqud\text{divide both sides by 3}\\\\\boxed{x=\dfrac{14}{3}\to\left(\dfrac{14}{3};\ 0\right)}$

Tomas ran a Lucky Dip stall.

oksian1 [2.3K]

Answer:

637

Step-by-step explanation:

Ticket ending 00= £12 * 7 = £84

Tickets ending 5 = £1.5 * 75 = £112.5

£84+£112.5=£196.5

Price money + Profit: £196.5+£163= 356

356/£0.5 = 719 total tickets sold

719- 82 (WINNING TICKETS) = 637 losing tickets sold

In the diagram of right triangle ABC shown below, AB = 14 and AC = 9. What is the measure of angle A to the nearest degree?

olga_2 [115]

This question is incomplete because it lacks the diagram of the right angled triangle. Find attached to this answer the diagram of the right angle triangle.

Answer:

d-50

Step-by-step explanation:

Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.

From the diagram, we are given

Hypotenuse = AB = 14

Adjacent = AC = 9

The measure of angle A to the nearest degree is calculated as:

cos θ = Adjacent / Hypothenuse

cos θ = 9/14

θ = cos -¹ (9/14) or arccos(9/14)

θ = 49.994799115°

To the nearest degree = 50°

Therefore,the measure of angle A to the nearest degree = 50°
