Answer:

9/10

1/2+2/5

Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10

1/2 ∗ 5/5 = 5/10

5/2∗ 2/2= 4/10

Since these fractions have the same denominator, we can just add the numerators

5/10+ 4/10 = 9/10

The sum of two numbers is 50 and the difference is 4
juin [17]

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

How would I translate this algebraic expression?
FromTheMoon [43]

Answer: \frac{5}{7} (2+\frac{6}{r} )

Step-by-step explanation:

Since, the quotient of 6 and r = \frac{6}{r}

The sum of two and the quotient of 6 and r

= (2+\frac{6}{r} )

And,  Five-sevenths of the sum of two and the quotient of 6 and r

= \frac{5}{7} (2+\frac{6}{r} )

Thus, the required expression is, \frac{5}{7} (2+\frac{6}{r} )

saul85 [17]

Answer:

  $7,358

Step-by-step explanation:

Assuming the interest is compounded annually, the amortization formula is useful here.

  A = Pr/(1 -(1+r)^-t)

A is the annual scholarship, P is the principal invested at rate r for t years.

  A = $100,000(0.04)/(1 -1.04^-20) = $7,358.18

The university could give $7,358 in scholarships each year.
