Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
Hope this helped :)
Answer:
11%
Step-by-step explanation:
The full circle graph represents 100% of the given population. All populations are given except for "three or more." Adding all percentages of each population should add up to 100%.
No absences (none): 23%
One absence: 45%
Two absences: 21%
Three more absences: unknown.
Let the variable x represent the unknown population.
23% + 45% + 21% + x = 100%
Combine like terms.
89% + x = 100%
Subtract 89% from both sides.
x = 11%
To put it more simply, subtract all the percentages from 100% to get the percent of the missing population. 100 - 23 - 45 - 21 = 11
