Answer:

13,88,22

On the first evening Jamie received 13 calls.

Step-by-step explanation:

Total number of phone calls received by Jamie over three evenings = 123

Let the number of phone calls received on the third evening = x.

The number of phone calls received on the second evening = 4*x.

The number of phone calls received on the first evening = x-9

Expressing in equation form:

\[x+4x+x-9=123\]

\[=>6x-9=123\]

\[=>6x=132\]

\[=>x=\frac{132}{6}\]

\[=>x=22\]

So Jamie received 22 calls on the third evening, 88 calls on the second evening and 13 calls on the third evening.

3/7 of the people living in the apartment building are men. 5/8 of the remaining are women. The rest are children. A total of 27
Vladimir [108]
People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x

y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280

So we have 280 people in the building.

check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women

so we have 120 men, 100 women and 60 children!

hope this is right! have a great. day

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Rudik [331]

Step-by-step explanation:

Given

The function is f(x)=x+4

for x_2>x_1, we will check the values of f(x_1) and f(x_2)

Take 3 and 4

f(4)=4+4\\f(4)=8

Similarly,

f(3)=3+4\\f(3)=7

Thus, f(4)>f(3)

Also, f'(x) is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.
