Why do you need a common denominator to work with some algebraic fractions and rational expressions?

Answer:

12=2.5h+4

Step-by-step explanation:

(1) Repetition allowed : There are 4 choices for both positions, so 4 × 4 = 16 2-digit numbers can be formed. (2) Repetition not allowed : There are 4 options for tens position, and three options for ones position. Therefore, 4 × 3 = 12 2-digit numbers can be formed.

Answer:

k=20

Step-by-step explanation:

ph*tomath (the app) is your friend btw because this would be really easy to solve using that but

solve for k:

simplify the left side as 310-210 then =100

so 100=5k

divide by 5 and k=20

Answer:

12

Step-by-step explanation:

We can try and get both sides to have a common denominator. If we multiply the left side by 4, we get 12/16=x/16. Here, it is clear that x=12.

Answer:

x is equal to 12/16

Step-by-step explanation:

If you divide 12/16 by 4 you will realize that it is equal to 3/4. Therefore x is equal to 12. That is a really explanation, but hope it helps!

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.

The diagram is given below.

Answer:

50th term is 164

Step-by-step explanation:

a(n) = 17 + 3(n - 1)

a(50) = 17 + 3(50-1)

a(50) = 17 + 3(49)

a(50) = 17 + 147

Answer:

x = 7

Step-by-step explanation:

The image below shows the relationship between secants chords and tangents.

Imagine that the letters in the image represent the numbers in the actually problem

E would equal 9

C would equal 12

and A would equal x

We would then use the same formula C² = E * ( E + A ) to solve for x , but once again instead of using letters we use the numbers in the problem

We would have 12² = 9( 9 + x )

we now solve for x

Step 1 simplify and distribute

12²=144

9 * 9 = 81

9 * x = 9x

we would then have 144 = 81 + 9x

step 2 subtract 81 from each side

144 - 81 = 63

81 - 81 cancels out

we now have 63 = 9x

step 3 divide each side by 9

63 / 9 = 7

9x / 9 = x

we're left with x = 7
