Answer:
1, 3, 4 i hope this helps ;)
Step-by-step explanation:
70+75+80+90+100=415
415/5=83
<span>After the lowest grade is dropped, Janet's average would be an 83%</span>
I believe the answer is 0.5 sorry if I’m wrong
If you convert the number on a percent,
then multiply the number by 100 with sign %
1.04 = 1.04 × 100% = <u>104%</u>
X + 6.38 = 15.75<span> would be the answer
x=9.37
for the first option, you are not adding 15.75 and x together.
for the second option, it is correct, because in the problem, it is giving the operation, 15.75-6.38=x. when you turn it do inverse operation, you get </span><span>x + 6.38 = 15.75.
for the third option, it doesn't make sense and it's not doing what the problem is asking for.
for the fourth option, you are not multiplying. you are subtracting </span>15.75 by<span> 6.38 to get x.</span>
