Answer:

x=7

Step-by-step explanation:

4(x + 4) = 7x - 5

Distribute

4x+16 = 7x-5

Subtract 4x from each side

4x+16 -4x = 7x-5-4x

16 = 3x -5

Add 5 to each side

16+5 = 3x-5+5

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

Two thirds the sum of 30 and a number is 26 write this statement out as an equation and solve
zloy xaker [14]

Answer:s

Step-by-step explanation:

Let the number be x

2/3(30+x) = 26

2(30+x) = 26(3)

60 + 2x = 78

2x = 78 - 60

2x = 18

x = 18/2

x = 9

Are the ratios 25/45 and 15/27 proportional? Explain.
liberstina [14]
Write them out as a fraction then reduce them. If theyre the same then its proportional.

25/45 can be cancelled down to 5/9

15/27 can be cancelled down to 3/9

So no theyre not.

Answer:

\theta=1.72  radians

Step-by-step explanation:

Arc length and radius is given. So, we need to know the arc length formula for a circle.

That is:

s=r\theta

Where s is the arc length

r is the radius

\theta  is the angle (IN RADIANS)

We have:

s = 15.5

r = 9

Now, we substitute and find the angle:

s=r\theta\\15.5=9\theta\\\theta=\frac{15.5}{9}\\\theta=1.72

The angle, in radians, in 1.72
