Answer:

x = - 3

y = 4

Step-by-step explanation:

x + y = 1 | (-3)

x + 3y = 9

- 3x - 3y = - 3

   x + 3y = 9

_____________

- 3x + x = 9 - 3

- 2x = 6

2x = - 6

x = - 3

- 3 + y = 1

y = 1 + 3

y = 4

Mia can run at a rate of 360 feet per minute. Approximately how many minutes would she take to run a 500-yard stretch of road an
tankabanditka [31]

Step-by-step explanation:

since we know, she can run 360 ft per minute, and we want to know how many minutes she would need to run 500 yards we need to find out how often 360 ft fit into 500 yards.

so,

500 yards / 360 ft

how can we make this division ?

help is given to us by taking us that 1 yard = 3 ft.

aha !

so, 500 yards = 500×3 ft = 1500 ft

therefore, our task now looks like

1500 ft / 360 ft

and this we understand and can do, right ?

1500 / 360 = 150/36 = 75/18 = 4 3/18 = 4 1/6 minutes

the closest answer option is therefore 4.2, meaning she would take about 4.2 minutes to run 500 yards.

I need help on the following questions.
Zigmanuir [339]
For the first one, you just need to divide the amount of feet by 3 to get the amount of yards (there are three feet in a yard). 

1431 / 3 = 476 2/3
 
The 102nd floor of the Sears Tower is 476 2/3 yards from the ground.

Second, you just need to multiply the amount of centimeters by 10 (there are 10 millimeters in a centimeter).

16 * 10 = 160

The butterfly has a wingspan of 160mm.

Third, the measurements are indeed 
7. =
8. =
9. <
10. >
11. > 
12. =

Fourth, you just need to know your conversion factors.
1. There are 3 feet in a yard. 42 / 3 = 14 yards
2. There are 1000 meters in a kilometer. 2350 / 1000 = 2.35 km
3. 12 inches in a foot. 18 * 12 = 216 inches
4. 10 decimeters in a meter. 289 * 10 = 2890 dm
5. 1760 yards in a mile. 1760 * 5 = 8800 yds
6. 10 millimeters in a centimeter. 35 * 10 = 350 mm

Hope that was helpful =)

There are 60 office suites in a downtown building. For how many office suites does company C service the computers? -Company A s
natima [27]
Company C services 16 office suites.

Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5.  Find a common denominator; 15 is the smallest:

1/3=5/15
2/5=6/15

5/15+6/15 = 11/15

This means that 1-11/15 = 4/15 of the suites are serviced by Company C.

4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16

HELP FAST WILL MARK BRAINLEIST
ValentinkaMS [17]

Step-by-step explanation:

The given inequality is

10 + 5x \leqslant 35

Subtract 10 from both sides

5x \leqslant 35 - 10

5x \leqslant 25

Divide both sides by 5 to get:

x \leqslant 5

We draw a closed circle at 5 and draw the arrow to the left.

See it in the attachment.
