Answer:
4c-8 or 4c+(-8)
Step-by-step explanation:
4xc- 4x2
Answer:
24 students
Step-by-step explanation:
So we started with 32 cups of juice.
Kahled drunk 2 cups so (32-2)=30 cups is left.
If x represents the number of students he receive juice and each student gets the same amount of juice which is 1.25 cups, then we have the equation
1.25x=30 to solve for x.
Divide both sides by 1.25:
x=30/1.25
x=24
24 students receive juice
7+5= 12 ones. Or one ten and 2 ones. They made 12.
Answer:
New mean length of these 17 people=11.62
Step-by-step explanation:
<em>Step 1: Determine the total length of children's fingers</em>
L=l×n
where;
L=total length (cm)
l=mean length (cm)
n=number of children
replacing;
L=6.7×6=40.2 cm
The total children's fingers length=40.2 cm
<em>Step 2: Determine the total length of adults fingers</em>
total length of adults fingers=mean length of adults fingers×number of adults
where;
mean length of adults=14.3
number of adults=11
replacing;
total length of adults fingers=(14.3×11)=157.3 cm
<em>Step 3: Determine the new mean length</em>
new mean length=total length of adults and children fingers/number of adults and children
where;
total length of adults and children fingers=157.3+40.2=197.5 cm
number of adults and children=11+6=17
replacing;
new mean length=197.5/17=11.62
