Answer:
Joe: 3 hrs
Janet: 6hrs
Step-by-step explanation:
joe takes x hours
so in 1 hr he does 1/x of the garden
janet takes 2x hours
so in 1 hr she does 1/(2x) of the garden
In one hour together they do 1/2 of the garden
1/x + 1/(2x) = 1/2
2/(2x) + 1/(2x) = 1/2
3/(2x) = 1/2
Cross multiply
6 = 2x
x = 3
Joe: 3 hrs
Janet: 6hrs
Answer:
All you have to do is find the rest of the percentage. Percentage adds up to 100%. So you will have to add the two percentages they gave you. 27+33=60%. Now you have to take away 60 from 100. 100-60=40%.
40%- That's the answer.
Hope this helps.
Radius = 1/2 * diameter = 5
Equation is (x - (-4))^2 + (y - 9)^2 = 5^2
(x + 4)^2 + (y - 9)^2 = 25 is the answer
You put them in fractions then cross multiple.
18/12 and 3/x so that's 36 equals 18x then you divide 36 by 18 which is 2.
On a number line, v would be all the numbers to the left of -3 (for example, |-4|=4 which is greater than 3) and all the values to the right of positive 3. Since it can't equal 3, v=-3 and v=3 are not included on the number line.
