√5(√10 + √3) = √(5 · 10) + √(5 · 3) =

= √50 + √15 = √(25 · 2) + √15 =

= √(5² · 2) + √15 = 5√2 + √15 ← the end

siw is a fourth as old as mother, and Mona is a fifth as old as mother. Mother is 22 years older than the two girls together. Ho

myrzilka [38]

Answer:

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

Step-by-step explanation:

Let

x ----> Siw's age

y ---> Mona's age

z ---> Mother's age

we know that

Siw is a fourth as old as mother

$x=\frac{1}{4}z$ ----> equation A

Mona is a fifth as old as mother

$y=\frac{1}{5}z$ ----> equation B

Mother is 22 years older than the two girls together.

$z=x+y+22$ ----> equation C

substitute equation A and equation B in equation C

$z=\frac{1}{4}z+\frac{1}{5}z+22$

solve for z

Multiply by 20 both sides to remove the fraction

$20z=5z+4z+440$

$20z-9z=440\\11z=440\\z=40\ years$

Find the value of x

$x=\frac{1}{4}(40)=10\ years$

Find the value of y

$y=\frac{1}{5}(40)=8\ years$

therefore

Siw's age is 10 years old

Mona's age is 8 yers old

Mother's age is 40 years old

What is the square of one half?

Vlad1618 [11]

Answer:

One-half squared is one-fourth.

Step-by-step explanation:

When you divide fractions, you multiply the first term by the reciprocal of the second term. In this example, instead of multiplying 1/2 by 1/4, you now multiply 1/2 by 4. Therefore, one half is equal to 2 fourths.

The bread is on sale for $1.50 so Erica is also going to buy candy or gum. Which can she afford?

Alborosie

Ok, so she started off with $5.00.

She bought milk for $2.99.

She buys bread, which costs $1.50.

Subtracting the money she wasted, the total would be $0.51.

The only thing she could buy is 5 pieces of gum for 25 cents.

Her change will be $0.26.

Hope this helps!
