From the information given, 4 added to the unknown number is equal to 2 times the unknown number when it is subtracted from 19.
Let the number be x
x + 4 = 19 - 2 (x)
We now expand and simplify the equation by placing unknown on one side and the known on the other side
x + 4 = 19 - 2x
x + 2x = 19 - 4
3x = 15
x = 15 /3
x = 5
Answer:
Choice B
Step-by-step explanation:
The range of a function refers to the set of y-values (dependent variable) for which a particular function is real and defined. From the graph given, the least possible value of y is -5 while the maximum value of y is 5. This implies that the range of the function is between -5 and 5 inclusive
The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A
If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.
8-2=6
John mowed 6 lawns!
For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!
6*3=18
John earned $18!
Hope I helped! :)
