3. We can see that
1+100=101
2+99=101
3+98=101
.................
and so on
From 1 to 100, there are 50 pairs that has the sum is 101
Z=101×50=5050
4. We can see that
1-2=-1
3-4=-1
5-6=-1
...........
and so on
There are 10 pairs that has sum is -1
Z= 10×(-1)=-10

At a local preschool there is s as ratio of 3 boys to every 4 girls. If their are 245 total preschoolers enrolled how many are b

Zepler [3.9K]

Number of boys enrolled is 105

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

Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls

There are 245 total preschoolers

Ratio of boys and girls = 3 : 4

Number of boys : number of girls = 3 : 4

Let the number of boys be 3x

Let the number of girls be 4x

Total number of preschoolers = 245

Therefore,

number of boys + number of girls = 245

3x + 4x = 245

7x = 245

x = 35

Number of boys = 3x = 3(35) = 105

Thus number of boys is 105

What equation represents the line that passes through points (1.-5) and (3 -17)?

zzz [600]

ALL LINES CAN BE REPRESENTED IN THE FORM $f(x) = ax+b$ .

We know that:

$f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5$

and

$f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17$

Observe that:

$3a+b = 2a+a+b = 2a+(a+b)$

So:

$2a+(a+b) =-17$

But we know that $a+b = -5$ , so:

$2a+(a+b) =-17$

$2a+(-5) = -17$

$2a = -12$

$a = -6$

Since:

$a+b = -5$

$(-6)+b = -5$

$b = 1$

So the line is:

$f(x) = 1-6x$
