Sum of brother and sisters age is 26. Four times the brothers age is subtracted from three times the sisters age, the difference
lana66690 [7]

Answer : The ages of the brother and sister are, 10 and 16 years respectively.

Solution :

Let the age of brother be 'x' and the age of sister be 'y'

There are two equations formed which are,

x + y = 26      ..........(1)

3y - 4x = 8     ..........(2)

First we have to multiple equation (1) by 4 and then added equation (1) and (2), we get the value of 'y'.

4x+4y+3y-4x=8+26\\\\7y=112\\\\y=16

Now put the value of 'y' in equation (2), we get the value of 'x'

3(16) - 4x = 8

4x = 40

x = 10

The age of brother = x = 10 years

The age of sister = y = 16 years

Therefore, the ages of the brother and sister are, 10 and 16 years respectively.

An extra-strength aspirin contains 0.500 g of aspirin. how many grains is this? (1grain=64.8mg)
Snowcat [4.5K]

By unit conversion, the aspirin contains 7.72 grains.

We need to know about unit conversion to solve this problem. The unit conversion can be used to convert a unit to another unit. It can be defined as

a = xb

where a is unit a, b is unit b and x is the constant of conversion.

From the question above, we know that

m = 0.5 gram

unit conversion

(1 grain = 64.8 mg)

Convert the unit conversion to 1 mg

1 grain = 64.8 mg

1/64.8 grain = 64.8/64.8 mg

1 mg = 1/64.8 grain

Convert the aspirin mass to grain

m = 0.500 g

m = 0.5 x 10³ mg

m = 0.5 x 10³ x 1/64.8 grain

m = 7.72 grain

The density of water is 1.00 gram/milliliter. What is the volume in milliliters of 1.00 mole of water? Express your answer to th
Kay [80]

Answer: 18.0152 milliliters

Explanation:

Hi, to answer this question we have to apply the next formula:

Water volume = water mass / water density

Since 1 mol of water weights 18.0152 grams

Replacing with the values and solving:

Water volume = 18.0152 g / 1 g /ml = 18.0152 milliliters

Feel free to ask for more if needed or if you did not understand something.

Magnesium and oxygen balanced
11Alexandr11 [23.1K]
2Mg+ O₂= 2MgO
The charge of Mg is+2 and the charge of Oxygen is -2. 2 oxygen atoms will have a charge of -4 so the Mg atoms have to equal +4. A coefficient of 2 for the Mg atoms will balance it out
