Wouldn’t you just add them?

If so it would be 80.

Or it could be 70.

Which of the following expressions are equivalent to \left(9\dfrac{7}{8} + 2\dfrac{4}{5}\right)-\dfrac{1}{2}(9 87 +2 54 )− 21

lora16 [44]

Answer:

$12\dfrac{7}{40}$

Step-by-step explanation:

The given expression is

$\left(9\dfrac{7}{8} + 2\dfrac{4}{5}\right)-\dfrac{1}{2}$

We need to find the simplified form of the given expression.

It can be rewritten as

$\left(9+\dfrac{7}{8} + 2+\dfrac{4}{5}\right)-\dfrac{1}{2}$

Combine integers and fractions separately.

$(9+2)+(\dfrac{7}{8}+\dfrac{4}{5}-\dfrac{1}{2})$

Taking LCM we get

$11+\dfrac{35+32-20}{40}$

$11+\dfrac{47}{40}$

In can be written as

$11+\dfrac{40+7}{40}$

$11+1+\dfrac{7}{40}$

$12+\dfrac{7}{40}$

$12\dfrac{7}{40}$

Therefore, the expression $12\dfrac{7}{40}$ is equivalent to the given expression.

Jasmine wants to earn $2,000 in simple interest through a

Ierofanga [76]

Answer:

$10000

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

P = 2000 / ( 0.05 × 4 ) = 10000

P = $ 10,000.00

The principal required to

accumulate interest of $ 2,000.00

on a rate of 5% per year for 4 years is $ 10,000.00.

» Which pair of numbers has an LCM of 60?<br> 2 and 12<br> 5 and 12<br> 6 and 12<br> 3 and 12

Mariana [72]

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because 12 can also be divided by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same, 12 can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5: 5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12: 12, 24, 36, 48, 60, 72

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.
