Which method would be more efiicient to solve the system y=1/2x and 2x+3y=28

1 answer:

6 0

Probably the subsitution method

y=1/2x
subsitute that fr y

2x+3(1/2x)=28
2x+3/2x=28
times 2 both sides
4x+3x=56
7x=56
divide by 7 both sides
x=8
sub back

y=1/2x
y=1/2(8)
y=4

(x,y)
(8,4)

Jerry is mowing his lawn .it takes him 1/6 of an hour to mow 3/20 of his years .what portion of the yard does jerry now per hour

Ber [7]

Given that Jerry mows 3/20 yards of lawn in 1/6 hour.

Now we have to found how much Jerry can mow per hour.

We know that "work" and "time" are in direct proportion so we can setup the ratio of work and time to easily find the required work.

$\frac{Portion \; \; of \; \; lawn \; \; mowed}{time}=\frac{\frac{3}{20}}{\frac{1}{6}}$

$\frac{Portion \; \; of \; \; lawn \; \; mowed}{1}=\frac{\frac{3}{20}}{\frac{1}{6}}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{3}{20}*\frac{6}{1}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{18}{20}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{9}{10}$

Hence final answer is $\frac{9}{10}$ yards.

Answer both please (middle school) (probability)

Hunter-Best [27]

Answer:

Step-by-step explanation:

There are two possible outcomes, heads and tails

Probability = Number of events over number of favorable outcomes

64 being the number of events and heads and tails being the number of favorable outcomes ( 2 )

64 / 2 = 32

Hence, the coin is likely to land on heads 32 out of the 64 times.
