Answer:16
Step-by-step explanation:
Let the number be X
Twice the sum of a number and 5
= 2X+5
Three times the difference of the number and 2
= 3(X - 2)
Since Twice the sum of X and 5 is equal to three times the difference of the X and 2, This means
2(X + 5 )= 3(X - 2)
2X +10 = 3X - 6
3X -2X = 10 + 6 = 16
X = 16
Check
2×(16+5) =3×(16-2)
2×21 = 3×14
42 = 42
To find the average, combine all the numbers together and divide by the amount there is.
-7 + 2 - 9 - 4 - 7 = -25
-25/5 = -5
-5 is your average temperature
hope this helps
Answer:
1015 widgets
First investigate how many widgets can machine A produce in 1 hour:
If it produces 435 in 3 hours, then it will produce one third of that in one hour:
In ONE (1) hour widgets
Therefore in seven (7) hours it will produce seven times the amount it does in one hour, that is:
widgets
f(-2)=4+6+2
f(-2)=12
Add -2 where all the x values are then solve
352 calls
Each day he makes 7 calls and 36 days have gone by so you'll multiply 36 and 7.
