Find three consecutive odd integers whose sum is 13 more than twice the largest of the three integers.
kicyunya [14]

Answer:

15, 17, 19

Step-by-step explanation:

Three consecutive odd integers can be represented by

x,  x + 2,  x + 4.  You add 2 to each one to get the next one. Fun fact: you would do the same thing if the problem said the integers were even!

The largest integer is x + 4, so the sentence in the problem translates to an equation (sum means to add the integers together):

x + (x + 2) + (x + 4) = 2(x + 4) + 13

Distribute the 2, then combine like terms.

x + (x + 2) + (x + 4) = 2x + 8 + 13

3x + 6 = 2x + 21

Subtract 2x.

x + 6 = 21

Subtract 6.

x = 15

The integers requested are 15, 17, 19.

Check:  Their sum is 51, which is 13 more than twice 19.

Solve the system 2x+4y=16 5x +3y=19 then find the value of y/x
AURORKA [14]

Answer:

I would change 2x+4y=24 into x=12–2y

To do that, divide both sides by 2 and then subtract 2y on each side.

After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.

Then solve.

3(12–2y)+2y=19

36–6y+2y=19

-4y+36=19

-4y=-17

y=4.25

Then, substitute y in either equation.

Either this:

3x+2y=19

3x+2(4.25)=19

3x+8.5=19

3x=10.5

x=3.5

Or:

2x+4y=24

2x+4(4.25)=24

2x+17=24

2x=7

x=3.5

Or you could solve it in the equation you created in the beginning:

x=12–2y

x=12–2(4.25)

x=12–8.5

x=3.5

The coordinates where the lines intercept are (3.5, 4.25).

Sorry for the long answer!

After writing part of his novel, Thomas is now writing 16 pages per week. After 4 weeks, he has written 85 pages. Assume the rel
d1i1m1o1n [39]

The initial value is 21 and rate of change is 16 pages per week

<em><u>Solution:</u></em>

Given that After writing part of his novel, Thomas is now writing 16 pages per week

After 4 weeks, he has written 85 pages.

Given that assume the relationship to be linear

Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + c

y = mx + c

where "y" is the number of pages written after 4 weeks

x = 4 weeks and m = 16 pages

Therefore,

85 = 16(4) + c

85 = 64 + c

c = 85 - 64

c = 21

Therefore, initial value is 21 and rate of change is 16 pages per week
