Answer:

x = 77, y = 63

Step-by-step explanation:

x - 5 = 72 ( corresponding angles )

x = 77

The 3 angles on the straight line sum to 180°, that is

x - 5 + 51 + y - 6 = 180, that is

72 + 51 + y - 6 = 180

117 + y = 180 ( subtract 117 from both sides )

y = 63

Juli2301 [7.4K]

Answer:

Step-by-step explanation:

Needs $500 Makes 7.50 and works 10 hours week.

7.50*10= $75.00 a week

500/75= 6.6 weeks or 6 weeks and 2/3 of a week. I'd round to 7 weeks.

75(x)=500 X= weeks needed.

75x=500 if you divide 500 by 75

x=20/3 or 6.6

Answer:

(11, 11)

Step-by-step explanation:

Solve by substitution:

1. set the equations equal to each other

$3x-22=-x+22$

2. simplify

$4x-22=22\\4x=44\\x=11$

3. substitute the value of x into an equation

$y=3(11)-22\\y=33-22\\y=11$

if A and B together can do a piece of work in 10 days and B along can do it in 15 days, how many part of the work does A complet

anzhelika [568]

Answer:

1/5

Step-by-step explanation:

Well work can be defined as: $work = rate \ *\ time$

where rate=amount of work that can be done in one unit of time

let a = rate of work A does in a day

let b = rate of work B does in a day

this means that: $10a + 10b=1$ where work=1 and it just means the entire job has been completed.

Since b can do it alone in 15 days, this means that: $15b=1$

If we divide by 15 here, we get the equation: $b=\frac{1}{15}$

We can now use this definition to substitute it into the first equation we made.

$10a + 10(\frac{1}{15}) = 1$

Multiply the 10 and 1/15

$10a+\frac{2}{3}=1$

subtract 2/3 from both sides

$10a=\frac{1}{3}$

Now divide both sides by 10

$a=\frac{1}{30}$

Now multiply this by 6, since we a represents the amount of work that can be done in a day, we want to find how many parts of the work can be done by a in 6 days

$6a=\frac{6}{30}$

Now divide both the numerator and denominator by 6

$a=\frac{1}{5}$

The Lakewood Wildcats won 5 out of their first seven games in this year. There are 28 games in the season. About how many games

allochka39001 [22]

Answer:

The total number of matches expected to be won by Lakewood Wildcats in this season is 20.

Step-by-step explanation:

The number of games played by Lakewood Wildcats = 7

Number of matches won by Lakewood = 5

or, the ratio of Won : Played = 5: 7

Total numbers of games in the season = 28

Let the Lakewood Wildcats win m number of games.

Here, ratio of Won Matches : Played Matches = m : 28

Now, by RATIO OF PROPORTIONALITY:

$\frac{5}{7} = \frac{m}{28}$

⇒ $m = \frac{28 \times 5}{7} = 20$

or, m = 20

Hence, the total number of matches expected to be won by Lakewood Wildcats out of total 28 matches is 20.
