So first you would substitute j and k in the expression.

7(0.5)+5-8(0.25)

3.5+5-2

It would equal 6.5

Hope this helps!

Solve for y, z, x or t: y+ y/a =b, if a≠−1
Vadim26 [7]

Answer:

  • y=ab/(a+1)

Explanation:

In this case, you need to solve for y in y + y/a = b, if s ≠ - 1.

This is how you do it step-by-step:

<u>1. Multiply all the equation by the common denominator</u>: a

y + y/a = b\\ \\ a(y + y/a = b)\\ \\ a(y + y/a) = ab

<u>2. Simplify</u>:

ay + ay/a = ab\\ \\ ay+y=ab

<u>3. Common factor:</u> y

y(a+1)=ab

<u>4. Divide both sides by a + 1</u>

y=ab/(a+1)

Write a recursive formula and an explicit formula for the following arithmetic sequence.
zysi [14]

Answer:

Recursive Formula: f(1) = 10, f(n) = f(n − 1) + 7 for n ≥ 2.

Explicit Formula: f(n)= 10+7(n-)

Step-by-step explanation:

Recursive Formula:  f(1) = first term, f(n) = f(n − 1) + d for n ≥ 2.

Explicit Formula: f(n)= f(1)+d(n-1)
