stiks02 [169]
The equation can be 5(x)=200
Or to solve u might want to use the formula 200/x=5
200 divided by 5 is 40
So 5 times 40 is 200

Explain how to solve the equation. 49= x/7
RoseWind [281]

49 =  \frac{x}{7}

<u>Multiply both sides of the equation by 7</u>

<u>49 \times 7 =  \frac{x}{ \cancel7}  \times  \cancel7</u>

<u>343 = x</u>

<u>x = 343</u>

Plz help me w/these three problems reasonably easy sixth grade math thank you!!!!!
ss7ja [257]
This is simple!
To begin with, arrange all the numbers in order.
#1
5, 5, 20, 20, 25, 30, 35
Mean:  add all the numbers together and divide it by how many numbers are there
5+5+20+20+25+30+35=140 
there are 7 numbers
Mean: \frac{140}{7} = 20
Median: The middle number, if the set of numbers have an odd number, then the one in between is the median, if there it is an even number, then the mean of the two in-between numbers is the median.
Median:  20
Mode: The most repeated numbers
Mode: 5 and 20
Range: Highest number - lowest number
Range: 35 - 5 
            30
#2
Order: 44, 48, 48, 49, 59, 61, 63, 68
Mean: 440 (sum of all numbers)
there are 8 numbers in total
\frac{440}{8} = 55
Median: there are 8 numbers so, the mean of the in-between numbers will be the median
49+59=108
2 numbers
\frac{108}{2} = 54
Mode: 48
Range = 68 - 44 = 24
