50(115-y) + 25y = 4125 [from eq2]
5750 - 50y + 25y = 4125 [distribute]
5750 - 25y = 4125
-25y = -1625
y = 65 [divide both sides by (-25)]
There are 65 small boxes.
Put that value into either equation (now, which is easier?) to solve for x:
x = 115 - y
x = 115 - 65
x = 50
There are 50 large boxes.
Step 1: Put a decimal point at the end of the number: <span><span>64090000000.
</span>Step 2: Move the decimal point 10 spaces to the left: </span><span>6.4090000000
</span>Number Part: 6.4090000000 aka 6.409⋅<span>10Exponent Part: 10
Answer: 6.409 x 1010</span>
Answer:
21-17=4
Step-by-step explanation:
like that?
2 to the third power is 2³
so 2 to the third power times -5 is 2³ * (-5)
which on simplification will be 8* (-5) =-40
Hello!
<span>To transform the normal, standard numbering to centric notation, simply remove the zeros prior to the point, and raise the remainder to the number of zeros in their negative form.
0.0078 = 7.8 * 10 -3.
