Answer:

8<x<12

Step-by-step explanation:

We know that sum of any two side of triangle is greater then 3th side, so we have:

x+8>4

x+4>8

4+8>x

i.e

x>-4

x>4

12>x

We can conclude that 4<x<12.

From the picture x is the biggest, x must be greater than 8.

So we have 8<x<12

Ray Of Light [21]

Answer:

Every day, 43% percent of people are added from the total number of people who receive the email

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

P(t)=a(1+r)^t

where

P(t) is the total number of people who receive the email

t is the time in days

a is the initial value

r is the rate of change

we have

P(t)=6(1.43)^t

so

a=6 ---> initial number of people who receive the email

(1+r)=1.43

solve for r

r=1.43-1\\r=0.43

Convert to percentage

0.43(100)=43\%

so

The daily percent change in the number of people who receive the email. every day is 43%

therefore

Every day, 43% percent of people are added from the total number of people who receive the email

a student bought a juice pouch for $2.50 and 3 bags of chips. the total cost was $5.05 write and solve an equation to determine
Wittaler [7]

First, write it as an equation

2.50+3x=5.05

Next, subtract 2.50 from both sides

2.50-2.50+3x=5.05-2.50

3x=2.55

Divide 3 on both sides

3x/3=2.55/3

x=0.85

The cost of a bag of chips is 0.85

hope i helped :D
