5÷ 3/4= what is the right answer
neonofarm [45]

You keep, change, and flip.

Keep 5, change ÷ into x, and flip 3/4 into 4/3.

5 x 4/3 = 20/3 = 6 and 2/3.

That's the answer: 20/3 or (6 and 2/3).

Hope this helps

Linear Equation, Need Solved Asap <3
s2008m [1.1K]

Step-by-step explanation:

y = 5x - 4

When x = 0, y = 5(0) - 4 = -4.

When x = 1, y = 5(1) - 4 = 1.

When x = 2, y = 5(2) - 4 = 6.

The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).

We now check the point (-5,-29):

(-29) : 5(-5) - 4

-29 : -25 - 4

-29 : -29 => -29 = -29.

Since Left hand side = Right hand side, the point (-5,-29) is a solution.

Hello!

Let O be the center of the sphere, A the tangency point and B the location of the satellite.

m<ABO = 1/2m(b) = 1/2 * 138 = 69

m<OAB = 90

m<AOB = 180 - 90 - 69 = 21

21 * 2 = 42

The answer is 42°

Hope this helps!
