Let the number be x, the square of x is x^2, then
The product of the square of x and 5 is 5x^2.
Answer:30
5x+130=6x+100
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+130=6x+100
Step 1: Subtract 6x from both sides.
5x+130−6x=6x+100−6x
−x+130=100
Step 2: Subtract 130 from both sides.
−x+130−130=100−130
−x=−30
Step 3: Divide both sides by -1.
−x
−1
=
−30
−1
x=30
Answer:
x=30
Only thing I can tell you is to use a corner to a piece of paper. The corner is 90 degrees. It's acute if the corner is bigger than the angle. Obtuse if its smaller.
Since 1 milligram = 0.001 grams you just have to multiply 75 milligram by 0.001 grams in order to get the grams.
75 x 0.001= 0.075 grams so the answer is F.
