Answer:
1.5 inches/ week
Step-by-step explanation
Given
Height of he plant = 3in
If the plant grows by 2in every week
The rate of change = Height of plant/weekly increase
The rate of change = 3/2 = 1.5 inches/ week
A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c
add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5
sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side
now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side
Answer:
2250
Step-by-step explanation:
We have, 14% × x = 315
or,
14
100
× x = 315
Multiplying both sides by 100 and dividing both sides by 14,
we have x = 315 ×
100
14
x = 2250
If you are using a calculator, simply enter 315×100÷14, which will give you the answer
Answer: x =168
Step-by-step explanation:I think it would be 80 plus 88 so its 168.
