Answer:
39 mg
Step-by-step explanation:
To get the number of milligrams, all we have to do is to find 130% of the RDA
mathematically, we have this as;
130% of 30
= 130/100 * 30 = 39 mg
Step 1; multiple equation 2 by -2: 14x+8y=-18
step2: subtract this new equation from equation 1 to eliminate x:
2y-8y=18-(-18)
-6y=36
y=-6
step 3: substitute y=6 in equation 2: -7x-4*(-6)=9, -7x=-15, x=15/7
Answer: -35
Step-by-step explanation:
You can check it by multiplying -3 and -35 you should get 105
Answer:
-1/y
Step-by-step explanation:
This quotient is the result when you divide y into -1: -1/y
