Answer:

your answers will be 12 and 7

Step-by-step explanation:

a few points to help that are related to numbers

Sum of two odd numbers will always be even.

Sum of two even numbers will always be even.

Sum of one odd and one even number will always be odd.

Let the both numbers be first and second.

According to the problem statement:

first + second = 19

first – second = 5

Add both equations:

first + second + first – second = 19 + 5

2 * first = 24

first = 24 / 2

first = 12

So from this we get first = 12, put this value in any equation i.e.

first + second = 19 (Put the value of first in this equation)

12+ second = 19

second = 19 – 12

second = 7

So, the numbers are 12 and 7.

Dr Wellbee advised his patients to drink 8 eight-ounce glasses of water everyday for every 50 pounds of weight. Kelby drank 168
BlackZzzverrR [31]
Kelby drank 168 glasses of water per week
i.e 24 glasses per day

Since 8  eight-ounce glass of water is for every 50 pounds.
1 eight-ounce glass is for = 50/8 pounds
and 24 glasses of water is for = 50*24/8
= 150pounds

So kelby probably weighs 150 pounds

AB=4x+3 and CD=24+5x find bc
madam [21]

Answer:

Step-by-step explanation:

1. use distribution factor

(4x+3)(24+5x)

4x times 24 = 96

4x times 5x = 20x

3 times 24 = 72

3 times 5x = 15x

2. combine like terms

96 + 72 = 168

15x + 20x = 35x

35x + 168 or 168 + 35x

I may be wrong please check my answer. I may have a lapse in my algebra, or I may have misunderstood the problem. But this is what I can give you to the best of my knowledge.

Estimate the solution of the system x+y=4 2x-y=6 by sketching a graph of each linear function. Then solve the system algebraical
Juli2301 [7.4K]

Answer:

(10/3, 2/3)

Step-by-step explanation:

You may find it easier to write these two equations x+y=4 2x-y=6 in a column:

x+y=4

2x-y=6

Adding these together will eliminate y:

3x = 10.  Then x = 10/3.

Substituting 10/3 for x in the first equation results in:

10/3 + y = 4

Clear fractions by multiplying all three terms by 3:

10 + 3y = 12

Then 3y = 2, and y = 2/3.

The solution is (10/3, 2/3)
