X= number of hours would it take Jason to wash the van by himself.
2x=number of hours would it take Wendy to wash the van by herserlf.
<span>we calcaulate the fraction of work by Jason during one hour </span>
x hours-----------------------------1 work
1 hour---------------------- fraction of work during one hour.
fraction of work during one hour=(1 hour * 1work) / x hours=1/x
we calculate the fraction of work by Wendy during one hour.
2x hours-----------------------------1 work
1 hour---------------------- fraction of work during one hour.
fraction of work during one hour=(1 hour * 1work) / 2x hours=1/2x
We can suggest this equation:
2 hours(fraction of work by Jason during one hour + fraction of work by Wendy during one hour)=1 work
2(1/x + 1/2x)=1
least common multiple=2x
2(2+1)=2x
2(3)=2x
6=2x
x=6/2
x=3
answer: 3 hours would ti take Jason to wash the van by himself.
Answer: -72m
Step-by-step explanation:
Simplify
Answer:
Remember the key word”factor” which means to multiply. Multiple all those numbers by 3!
Step-by-step explanation:I’m going to do 2 of them and you can do the last one (2,1)x3= the dilation (6,3). (3,0)x 3 gives the dilation (9,0). (1,-2)x3 gives the dilation of (3,-6). See it’s very easy.
Answer:
Step-by-step explanation:
The given expression is
The exponent property
Applying this exponent property, we have
Now, the given numeric values are x = 9, y= 8, and z= 16
On substituting these values in the simplified expression, we get
This can be further simplified by writing
Now, applying the product rule of exponent:
Answer:
5+ 20 is the first thing that you do in the equation you do 5+20x3 then you do minus 12 then you can solve the equation straight across. you follow the rule PEMDAS. parenthesis, exponents, multiplication, division, addition, subtraction.
