What is the solution to the system of equations?
y = 2x + 3
y = -x +8

Answers

Answer:

x= 5/3

Step-by-step explanation:

You would set the equations equal to each other, so 2x + 3 = -x + 8. Then, you would add the x to the 2x making it 3x. That makes your equation 3x + 3 = 8. Then you subtract the 3 making the equation 3x = 5 and then you would divide the 3 making your answer 5/3.

Answer:

x = 18

Step-by-step explanation:

10  − 3x = − 2 (x + 4)

=> 10  − 3x = -2x - 8

=> x = 18

Hoped this helped.

Answer:

x = 18

Step-by-step explanation:

10 - 3x= -2(x+4)

First, we solve inside the parentheses.

10 - 3x= -2x - 8

Like terms:

-3x + 2x= -10 - 8

-x/-1 = -18/-1

x = 18

Answer:

y = 12

x = 4.4

Step-by-step explanation:

Scale factor is calculated by comparing the opposing side lengths and writing them as a fraction:

8/20 = 2/5 is the scale factor now to find the value of x and y we can use this scale

y/30 = 2/5 cross multiply expressions

5y = 60 divide both sides by 5

y = 12

same goes for x:

x/11 = 2/5 cross multiply

5x = 22 divide both sides by 5

x = 4.4

4800 persons run a marathon, 1200 reach the finish line. What is the percent of people reach the finish line at the marathon?

Answers

Answer: 25%

Step-by-step explanation: So first make the number of people who ran the marathon and the number of people who finished the marathon into a ratio

1200:4800

then make that into a fraction, 1200/4800

then make the percent of people who reached the marathon into a fraction, using 100 as the denominator and a variable as the numerator.

for example. p/100 (p, represents the percent)

then cross multiply.

1200x100=1200000

Last divide 1200000 by 4800 to get 25%.

1/3 * 15 crates = 5 crates

Answer: 5 crates

Answer:

Step-by-step explanation:

   

15 is to x as 4500 is to 1500, or 15 is to x as 3 is to 1.  Then x = 3 (crates)

Determine if the point is a solution to the system of linear equations [tex] \huge \{{ \large \begin{array}{} 2x + 3y = 2 \\ 6y = 5 - 4x \end{array}} [/tex] ​

Answers

Answer:

The system has no solutions.

Step-by-step explanation:

If you stare at it for the bit you can tell the system is impossible. Let's see why:

First of all, rewrite the second equation by bringing all unknowns on the LHS:

[tex]4x+6y=5[/tex].

Then take twice the first equation, doubling every coefficient:

[tex]4x+6y=4[/tex] See how the LHS is the same? The system is asking you to find a quantity (4x+6y) which is at the same time equal to four AND five - emphasis on that "and" - which is obviously impossible, because it implies that 4=5. So the point - which you didn't provide - is not a solution. Nor is any other point.

HOW DID THE MAN LEARN TO SURVIVE THROUGHOUT HIS EVOLUTION SINCE THE BEGINNING OF HIS EVOLUTION? In this excerpt from "A Modest Proposal" by Johnathan Swift, what does the author list?I can think of no one objection, that will possibly be raised against this proposal, unless it should be urged, that the number of people will be thereby much lessened in the kingdom. This I freely own, and 'twas indeed one principal design in offering it to the world. I desire the reader will observe, that I calculate my remedy for this one individual Kingdom of Ireland, and for no other that ever was, is, or, I think, ever can be upon Earth. Therefore let no man talk to me of other expedients: Of taxing our absentees at five shillings a pound: Of using neither cloaths, nor houshold furniture, except what is of our own growth and manufacture: Of utterly rejecting the materials and instruments that promote foreign luxury: Of curing the expensiveness of pride, vanity, idleness, and gaming in our women: Of introducing a vein of parsimony, prudence and temperance: Of learning to love our country, wherein we differ even from Laplanders, and the inhabitants of Topinamboo: Of quitting our animosities and factions, nor acting any longer like the Jews, who were murdering one another at the very moment their city was taken: Of being a little cautious not to sell our country and consciences for nothing: Of teaching landlords to have at least one degree of mercy towards their tenants. Lastly, of putting a spirit of honesty, industry, and skill into our shop-keepers, who, if a resolution could now be taken to buy only our native goods, would immediately unite to cheat and exact upon us in the price, the measure, and the goodness, nor could ever yet be brought to make one fair proposal of just dealing, though often and earnestly invited to it.A. reforms that had failed to improve Ireland's situationB. the unrealistic measures discussed by Irish government officialsC. viable measures that could improve Ireland's situationD. measures that would help unify the populace of Ireland
