Answer:

n ≥ -9

Step-by-step explanation:

Let n = the number

8 less than a number means "n – 8", but

8 less a number means "8 – n," so

8 – n ≤ 17 Subtract 8 from each side

-n ≤ 9 Multiply each side by -1

n ≥ -9

Note: When we multiply by a negative number, we must reverse the inequality.

Check:

Try n = -8.

8 – (-8) ≤ 17

8 + 8 ≤ 17

16 ≤ 17

True.

Write and solve the equations. A number y is five less than thirteen.

Genrish500 [490]

We can follow the following steps to make an equation and solve it.

Step 1:

five less than 13 means we have to subtract 5 from 13

so it becomes 13-5

Step 2:

A number y is five less than thirteen.

Now in algebraic expressions, "is" stands for "="

So we have:

$y=13-5$

Step 3:

Solving the equation to find y.

$y=13-5$

Subtracting 5 from 13, we get :

y=8

Answer:

For the given equation the solution is y=8.

5/6 is not the definite ratio, when you take a larger sample size it could be off by a bit like 499/600 or 501/600

If f(1) = 10 and f(n) = f(n = 1) – 4 then find the value of f(5).

svetoff [14.1K]

Given:

$f(1)=10$ and $f(n)=f(n-1)-4$ .

To find:

The value of f(5).

Solution:

We have,

$f(n)=f(n-1)-4$

For $n=2$ ,

$f(2)=f(2-1)-4$

$f(2)=f(1)-4$

$f(2)=10-4$

$f(2)=6$

For $n=3$ ,

$f(3)=f(3-1)-4$

$f(3)=f(2)-4$

$f(3)=6-4$

$f(3)=2$

For $n=4$ ,

$f(4)=f(4-1)-4$

$f(4)=f(3)-4$

$f(4)=2-4$

$f(4)=-2$

For $n=5$ ,

$f(5)=f(5-1)-4$

$f(5)=f(4)-4$

$f(5)=-2-4$

$f(5)=-6$

Therefore, the value of $f(5)$ is $-6$ .

If the average of 12 consecutive odd integers is 328, what is the least of these integers

yanalaym [24]

X+1+x+2+x+3+x+4+x+5+x+6+x+7+x+8+x+9+x+10+x+11+x+12/12
12x+78/12 = 132 times 12 is
12x+78 = 1,548 minus 78
12x = 1,506 divide by 12
x = 125.5 I believe is the answer, sorry if it is wrong
