Answer:
98
Step-by-step explanation:
147/3=49x2=98
Answer:
$154
Step-by-step explanation:
First, we need to find out how much Dale will make for 1 hour of work which means we need to divide $252 by 18 which is 14. Next, to find out how much he will make for 11 hours at work, we need to multiply 11 by 14 which is $154.
Here are the equations:
$252÷18=$14
$14×11=$154
The absolute value gives the positive value of any given number inside the symbol. The absolute equation is,
2.5 = I d - 2I
The values of d can be calculated through,
2.5 = d - 2
d = 4.5
Also,
-2.5 = d - 2
-2.5 + 2 = d
d = -0.5
Thus, the maximum value of the temperature is 4.5 and the minimum value of the temperature is -0.5.
Answer:
2m - 20
Step-by-step explanation:
Given that:
First week minutes = m
Second week minutes = (2 * first week minutes - 20)
Second week = 2m - 20
Therefore, the expression for the number of practice minutes for the second week is :
2m - 20
