X=36 because 1/3 times 36 equals 12
Vlada [557]3 years ago
6 0

The answer is x=36 and I will teach you how to slove for it.

Steps:

\frac{1}{3}x+9=21 \\ \\\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides} \\\frac{1}{3}x+9-9=21-9 \\ \\\mathrm{Simplify} \\\frac{1}{3}x=12

So yes you have done everything right up to this point, but you missing a step

\mathrm{Multiply\:both\:sides\:by\:}3: \\3\cdot \frac{1}{3}x=12\cdot \:3

All whole numbers that we work with in math are really just \frac{Any\ Number}{1} So we cross multiply 3, aka:\frac{3}{1} by \frac{1}{3}

\frac{3}{1} *\frac{1}{3} = 1 and also 12*3=36

Now if we simplify we are just left with x=36

If you find anything wrong with my answer just let me know, and I can guarantee that I will come back and rework my math. Thanks! :-)

Write the number five million four thousand three hundred in standard form
valentinak56 [21]

Written numerically, the number you stated is written as:

5,004,300

Standard Form (Scientific Notation) numbers are written as a decimal (n.m) such that there is [normally] only one digit (n) to the left of the decimal point, and the rest of the number (m) to the right (with a possible limit). If there is only a single digit in the whole number then the value on the right is a zero (n.0).

To show that the value shown has shifted its decimal point position, the number of decimal positions shifted is shown after the number as a 10’s multiplied to the power of the number of positions shifted.

e.g., 102 = 102.0 = 1.02 (decimal point shifted left two places. If smallest digit is 0 then ignore it UNLESS it’s the ONLY digit!!)

1.02*10^2(2 Decimal shift to the left)

1.02*10^2

So, for the number asked in the question:

5,004,300 = 5,004,300.0

Left shift 6 times to largest digit = 5.004300

5.004300 (show the shift multiplier: 10^6)

5.004300*10^6

What is the probability of rolling a 4 on a number cube and then flipping a head on a coin?​
spin [16.1K]

Answer:

I think it's 1/6 for the cube and 1/2 for the coin. so it would be 2/8 which would be 1/4 simplified, so in decimal form the probability is .25
