Answer:
-22/15
Step-by-step explanation:
Okay, so, find a common multiple of 3 and 5. best way to find one is to multiply them. 3 x 5= 15. Now you have to make the numerators equivalent.
-2/3 = -10/15
-4/5 = -12/15
-10+-12=-22
Answer:-22/15
I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
Answer:
45
Step-by-step explanation:
These work problems are always done in terms of fractions ie if both (Kevin & Eric) took 30mins to mow and Kevin took 1.5hrs (90mins) alone then we can make an equation like below
1/time took for both = 1/time took for Kevin + 1/time took for Eric
1/30 = 1/90+1/x ==> calling time took for Kevin x
solving the above 1/x = 1/30-1/90
1/x=2/90
x=45
