5x-2y=30

complete the missing value in the solution to the equation
PLZZZZ HELP
(8,_)

Answers

Answer 1

Answer:

(8,5)

Step-by-step explanation:

x=8,

5(8)-2y=30

40-2y=30

40-30=2y

10=2y

y=10/2

y=5

Answer 2

Answer:

y=5

Step-by-step explanation:

If x=8, you plug it in and the equation is 5(8)-2y=30. If you solve it further, it is 40-2y=30. If you ignore the 2y for now, 40 minus what equals 30? The answer is 10 so you look at 2y and determine how you can multiply 2 to get 10. The answer is 5 so the full equation is 40-10=30.

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian's first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Answers

Answer:

21.9 feet

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Given parameters

Altimeter of vivian at its lowest point = -9.6 feet

Altimeter of vivian at the top of the wheel = 12.3feet

Note that the sea level is at 0 feet.

change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:

= (12.3-0)+(0-(-9.6))

= 12.3+(0+9.6)

= 12.3+9.6

= 21.9 feet

From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.

The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.

Answer:Hide Sample Answer

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Step-by-step explanation:Hide Sample Answer

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Carlos biked StartFraction 139 over 8 EndFraction miles on Saturday and StartFraction 135 over 7 EndFraction miles on Sunday. On which day did he ride further and by how much?

Carlos rode further on Sunday by 3 and StartFraction 51 over 56 EndFraction miles. Carlos rode further on Sunday by 1 and StartFraction 51 over 56 EndFraction miles.

Answers

Answer:

Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.

Step-by-step explanation:

Carlos covered distance on Saturday [tex]=\frac{139}{8}[/tex]

He covered distance on Sunday = [tex]\frac{135}{7}[/tex]

Equivalent fractions:

[tex]\frac{139}{8} \times \frac{7}{7}=\frac{973}{56}\\ \frac{135}{7} \times \frac{8}{8}=\frac{1080}{56}[/tex]

So,[tex]\frac{1080}{56}>\frac{973}{56}\\ \frac{135}{7}>\frac{139}{8}[/tex]

So, He covered more distance on Sunday

Difference between distances =[tex]\frac{1080}{56}-\frac{973}{56}=\frac{107}{56}=1\frac{51}{56}[/tex]

So, Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.

A railroad car container can hold 42,000 pounds. Mr. Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container? Explain. (each oven weighs 200 pounds)

Answers

Answer:

THe number of freezers that can be shipped along with 50 ovens is 40

Step-by-step explanation:

total weight of ovens being shipped is 18000 lb. and in order to find the excess weight we have to subtract the ovens weight and the total carrier weight.

equation is:

42,000 - 18000= 24000 lbs.

you then divide the left over pounds by the weight of the freezers to get the total amount of freezers that can be put into a railcar.

24000/600=40

So 40 freezers and 90 ovens can fit within one railcar.

Second practice time compared to first practice time
Joshua

Kedwin
–0.97
Leila

Miguel
+1.1
Nicole
–0.87

Maya claims that the runners’ order of most improved to least improved is Miguel, Joshua, Nicole, Leila, and Kedwin. Which statement describes whether Maya is correct?
Maya is correct because she compared each digit in the same place value. Miguel added the most time to his sprint so he is most improved.
Maya is incorrect because –0.87 < –0.95 < –0.97. Runners that decrease times are improving, and those that add time are not improving.
Maya is incorrect because 1.1 < 1.03. She should switch the order of Joshua and Miguel because Joshua added more time to his run.
Maya is incorrect because she listed the runners from least improved to most improved. Runners that decreased times are improving, and those that add time are not improving.
