7x+3+6x+11 i need help solving this problem

1 answer:

8 0

Step-by-step solution:

7x + 3 + 6x + 11 = 0

7x + 6x + 11 + 3 = 0

13x + 11 + 3 = 0

13x + 14 = 0

13x = 0 - 14

13x = -14

x = -14 / 13

x = -1.077 approx.

Hope it helped,

White raven [17]

Answer:

Width: 85 yards

Length: 95 yards

Step-by-step explanation:

Ok, so we need to make an equation for this problem. Let's call the width, w. We know that the length is 10 more than the width, so we can call it w +10.

180 = w + w + 10

Now, i order to isolate the w's we need to subtract 10 from each side.

170 = 2w

Now, we just have to divide by 2 on both sides.

W = 85

So we now know that the width is 85 and because the length is 10 more, the length is 95 yds.

Ashirt button has a diameter of 0.61 cm. Which of these is an approximate measurement of the circumference of the button?

Aleonysh [2.5K]

Answer:

1.92cm

Step-by-step explanation:

Circumference of a circle is computed using the formula:

$C=2\pi r$

Where:

r = radius

π = 3.14

Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.

We can then use the diameter to solve for the circumference by using the formula"

$C = \pi d$
