Answer:
a=55
Step-by-step explanation:
This question is asking for you to find the whole (a), given a part (11). This can be done through multiplication. 20% is 1/5 of 100%. This means to find the whole number, you should multiply the part by 5. 11*5=55. So, a must equal 55.
We can check this answer by working backward. Do this by finding 20% of 55, and checking to see if it is 11. To find a percentage of a number, multiply that number by the percent in decimal form. So, 20% of 55 is equal to 0.2*55, which is 11. Therefore, the answer is correct.
F should be -1, 6
E should be -4, 2
D should be -4, 9
Answer:
Step-by-step explanation:
Subtitute y in the first equation.
Now replace x in either equation to find y.
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
