<span>7x420
= 7( 400 + 20)
=2800 + 140
=2940
</span>
Answer:
1648
Step-by-step explanation:
5/9 are girls. The 9 represents the total.
Set up a proportion and you have
5/9 = ?/3708
3708/9=412
412x5= 2060 girls
3708-2060= 1648

<em><u>Solution:</u></em>
<em><u>Given that,</u></em>

We have to write in simplest form
<em><u>Use the following law of exponent</u></em>

Using this, simplify the given expression

Thus the given expression is simplified
1.
<span>1.5x-1 > 6.5
1.5x>1+6.5
</span>1.5x>7.5, divide by 1.5
x>5, is represented by the region to the right of the vertical line x=5
2.
<span>7x+3 < -25
7x<-25-3
7x<-28, divide by 4:
x<-4
</span>x<-4, is represented by the region to the left of the vertical line x=-4
