Answer:
7) 7<x<17
8 2.1<x<4.1
9) 0<x<54
10) 7.9<x<35.9
Step-by-step explanation:
you solve by finding the smallest side lengrh which will be the longer length- the shorter, as if the triangle were extremely tiny and all the sides were touching but the third would only be able to be as short as the difference, then for the maximum length as if the triangle were stretches out as much as possible, you add together the lengths because that's the furthest the third could stretch out, remember they will always be less then or greater then, never equal too as well, they can't reach that length other wise it would just be a line
<u>Answer-</u>
<em>The value of y is
when x=7 and z=4.</em>
<u>Solution-</u>
As given in the question, y is directly proportional to x, so
-----------------1
And also y is directly proportional to z, so
-----------------2
Combining equation 1 and 2,

Where,
k = proportionality constant
When x=6 and z=1, y=4. Putting theses values,




Now, we have to find the value of y, when x=7 and z=4


Therefore, the value of y is
when x=7 and z=4.
Answer:
− 19x + 12
Step-by-step explanation:
Answer:
The answer is 24
Step-by-step explanation:
Since the population after x hours is 2x, then after 12 hours, we'll substitute x = 12 into the function.
The population becomes 2 x 12 = 24
Answer:
14000:21000
Step-by-step explanation:
2:3 = 2x + 3x
2x + 3x = 35,000
5x = 35,000
x = 35,000/5
x = 7000
2x = 7000 * 2
= 14000
3x = 7000 * 3
= 21000
