Answer:

r = 13

Step-by-step explanation:

As the vertically opposite angles are equal,

8r + 6 = 9r - 7

<u>Now you can find the value of r.</u>

8r - 9r = -6 - 7

-r = -13

r = 13

Hope this helps you :-)

Let me know if you have any other questions :-)

Answer:

Step-by-step explanation:

1. You can use a calculator if your knowledge of arithmetic fails you.

... 98 +17 +37 -176 = 152 -176 = -24

___

2. -37/8 = -(32 +5)/8 = -4 5/8 = -4.625

This number is on the left side of zero on the number line, but is slightly closer to zero than -4.63, so is "greater than" -4.63.

The gravitational attraction between two masses varies inversely as the square of the distance between them. If the attraction f

pashok25 [27]

Answer: Option a) 33 1/3 lbs

Solution:

Attraction force (F) varies inversely as the square of the distance between them:

F=k/d^2

Constant of proportionality: k

Distance between the two masses: d

F=75 lbs when d=8 feet

Replacing in the formula above:

F=k/d^2

75 lbs=k/(8 feet)^2

Squaring in the denominator:

75 lbs=k/(64 feet^2)

Solving for k: Multiplying both sides of the equation by 64 feet^2:

(64 feet^2)(75 lbs)=(64 feet^2)[k/(64 feet^2)]

4,800 lbs*feet^2=k

k=4,800 lbs*feet^2

F=k/d^2

F=4,800 lbs*feet^2/d^2

Find the attraction when the masses are twelve feet apart:

F=?

d=12 feet

Replacing in the formula:

F=4,800 lbs*feet^2/(12 feet)^2

Squaring in the denominator:

F=4,800 lbs*feet^2 / (144 feet^2)

Dividing:

F=(4,800/48)/(144/48) lbs

F=100/3 lbs

F=(99+1)/3 lbs

F=(99/3+1/3) lbs

F=33 1/3 lbs

Solve the equation for c.

Ede4ka [16]

Answer = 8

Because:

c(c + 3) - c(c-4) = 9c - 16
c^2 + 3c - c^2 + 4c = 9c - 16
3c + 4c = 9c - 16
7c = 9c - 16
7c + 16 = 9c
16 = 2c
8 = c
