Answer:
4.5 ≤x<4.55
Step-by-step explanation:
for whole number
It has to be 4.5 or greater to round to 5 on the low end
It has to be less than 5.5 to round to 5 on the high end
for tenths
If has to be 4.45 or greater to round to 4.5 on the low end
It has to be less than 4.55 to round to 4.5
We take the more restrictive limits to define the number
The number must be between
4.5 ≤x<4.55
Y = -5/2(x + 4) + 7
y = -5/2x + (-10) + 7
y = -5/2x - 3
What are the option? If there are none
then you would take the two fractions and multiply the <span>denominators thus making a new fractions. This is called finding the common denominator.
</span>Ex: 1/2 and 2/3 would have a CD of 6.
<span>So, you would rename them 3/6 and 4/6</span>
Answer:
Equation: $1.67n=C
Step-by-step explanation:

Answer:
100 students
Step-by-step explanation:
10% of students in 7th grade ----- 10 students
<em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
1% of students in 7th grade ----- 10 ÷10= 1 student
<em>×</em><em>100</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
100% of students in 7th grade ----- 1 ×100= 100 students
