45 1/4-> 45.25 * .5 = 22.625 = 22 5/8
gusset plate :
5 3/4 -> 5.75 * .5 = 2.875 = 2 7/8
3 1/2 -> 3.5 * .5 = 1.75 = 1 3/4
47 1/4 -> 47.25 * .5 = 23.625 = 23 5/8
2 * .5 = 1
3 + 4 = 7
84 ÷ 7 = 12 = 1 (in terms of the ratio)
12 × 3 = 36, which is the answer
Hope this helps :)
To find x just change the <span>> to a =
</span><span>3x-7=5
add 7
3x=12
then divide by 3
x=4

Answer:
Option B is tge right answer.
3.07/10⁴= 0.000307
Short answer A
This one is exactly the same (with number changes) as the last one. You cannot use t which is in time, to mix with pure numbers which in this case is grams. That means that both C and D are incorrect.
Now as with the last one, are you going to raise e to a minus number or a plus number? Remember that if e is raised to a plus number, the sample in this case will increase. You are watching a radioactive decay. The number has to be smaller. So B is eliminated. There is only one answer left and that's A. It should be correct.
