28 because you must subract 22 from both sides

If Ronald is 22 years older than his son, and their ages sum up to 50 then we should first subtract 22 from 50 (being the age difference) and we're left with 28 and 22 divided by 2 is 14 which we can agree is Ronald's son's age now we add the earlier 22 we subtracted to 14 and it gives us 36 which is Ronald's age, so Ronald is 36 years old.
Hope it helps

Brownies

270

Cooldies

384

Step-by-step explanation:

Brownies

simply multiply the 18 by 3 we get 54 and if we multiply 54 by 5 we get 270.

we multiply it by 5 because in series it skip 1 number to multiply next.

Cooldies

first we multiply 16 by 2 we get 32.

next we multiply 32 by 3 we get 96.

and next we multiply 96 by 4 we get 384.

Simply increment in multiplication.

A batting machine uses an automatic baseball feeder. During baseball

Inessa05 [86]

The feeders in battling machine are represented in proportions and fractions.

The equation that represents the problem is: $\mathbf{\frac 16x + 15 = \frac 23x}$
The feeder can hold 30 baseballs, when full

The given parameters are:

$\mathbf{Initial = \frac 16x}$ ------ 1/6 full

$\mathbf{Additional = 15}$ --- baseballs added

$\mathbf{Final = \frac 23x}$ ---- 2/3 full

So, the equation that represents the problem is:

$\mathbf{Initial + Additional = Final}$

So, we have:

$\mathbf{\frac 16x + 15 = \frac 23x}$

The number of baseballs it can hold is calculated as follows:

$\mathbf{\frac 16x + 15 = \frac 23x}$

Multiply through by 6

$\mathbf{x + 90 = 4x}$

Collect like terms

$\mathbf{4x - x = 90 }$

$\mathbf{3x = 90 }$

Divide through by 3

$\mathbf{x = 30 }$

Hence, the feeder can hold 30 baseballs, when full

How do you simplify on number 1?

Dennis_Churaev [7]

Okay. On the part that's not the whole number, see how the top number is BIGGER than the bottom? That means that it's not simplified. In order to make it simplified, you have to take a whole out of the pat that's not a whole number. Since the denominator is 12, the whole is 12/12. So, subtract it from the 13/12.

13/12-12/12=1/12

Now, since you found a whole inside of the fraction you have to add 1 to the whole number.
5+1=6

So, the answer is 6 1/12.

Thanks for the points!
