x x=ly y=2x-2
you need use solving systems substitute​

Answers

Answer 1

Answer:

3

Step-by-step explanation:

If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.

Not what I really think it might be, but I hope it helped you!

x = 70

Step-by-step explanation:

The 2 given angles are same- side interior angles and are supplementary, that is sum to 180° , then

45 + 2x - 5 = 180, that is

Amy and Ben share £21 between them in the ratio 5 : 2. How much does Amy get?

(Im really sorry I just don't understand ratio.)

Answers

Answer:

✑ [tex] \underline{ \underline{ \sf{First ,\: Let's \: learn \: about \: the \: ratio}}} : [/tex]

Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = [tex] \sf{ \frac{30}{40} = \frac{3}{4} = 3:4}[/tex] and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : [tex] \sf{ \frac{a}{b}} [/tex] is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.

✎ [tex] \underline{ \underline{ \sf{Now \: let's \: solve : }}}[/tex]

☪ [tex] \underline{ \sf{Solution}} : [/tex]

£ 21 is to be divided between Amy and Ben in the ratio 5 : 2. So, let Amy get £ 5x and Ben get £ 2x.

Then , According to the question , [tex] \text{5x +2x = 21}[/tex]

Solve for x :

⇝ [tex] \sf{7x = 21}[/tex]

⇝ [tex] \sf{ \frac{7x}{7} = \frac{21}{7} }[/tex]

⇝ [tex] \sf{x = 3}[/tex]

The value of x is 3. Now , substitute the value of x in 5x :

Amy received £ 5x = 5 × 3 = £ 15 .

Answer:

-0.9

Step-by-step explanation:

First we have to distribute. -1 times t is -1t and -1 times 8 is -8. Now, our equation will look like this: -1t - 8 = -7.1  

Next, we have to carry our -8 to the other side of the euqation. So, we have to plus 8 on both sides. -7.1 plus 8 is 0.9. Now, our equation will look like this,

-1t = 0.9.

Lastly, we have to divide -1 from both sides. 0.9 divided by -1 is -0.9. So therefore, t = -0.9.

Find the total amount given the original price and tax rate. Round to the nearest cent if necessary.
$15.25,7%

Answers

Given:

Original price = $15.25

Tax rate = 7%

To find:

The total amount.

Solution:

We know that,

Total amount = Original price + Tax

According to the question,

Total amount = 15.25 + 7% of 15.25

[tex]\text{Total amount}=15.25+\dfrac{7}{100}\times 15.25[/tex]

[tex]\text{Total amount}=15.25+1.0675[/tex]

[tex]\text{Total amount}=16.3175[/tex]

Round to the nearest cent (two decimal places).

[tex]\text{Total amount}\approx 16.32[/tex]

Therefore, the total value is $16.32.

With anger and pain, but always see yourself as number one, Do what you think is right for yourself and other, Even though some decisions you make will be for yourself.Strong:We are strong, we all carry great feelings for the ones we love, if they are not strong, help and carry them to the end. People need to be strong in times of need, or maybe just in general, people who are not strong need people who are, to help them lead the way, till both are equally strong, and together people and people, strong or weak either way can make great deeds in life, and immortal marks in the world. Trees:Leaves fall to the ground, like a old tree losing its memories,Sap drips on cars, and onto the ground, from the face of the tree, like its crying.It sways in the wind, trying to keep its balance, and to stay strong,The wind rustles through the branches and leaves, giving advice and messages,Carved scars, in the hard, tough bark of a tree.We, us people are trees of our own, as we grow old, we forget our memories, but we always make more, in time.We cry, and produce our feelings, and they drip, into or onto others.We sway, as we try to stay strong, and to keep our balance.And we produce advice and messages, from our minds, as we think, in deep thought.We are trees, strong, tall, structures, that live life, produce, and die off. Friends:There's this little thing called friendship.I experience it every day,And will always be thankful that I have friends,Because they have helped me along the way.A friend is a flashlight in the dark, or a somebody who will hold your hand in the dark,A rainbow after the storm,The sunshine after a cold, damp day,The glue when you are torn.I have friends I love like sisters and brothers.(I know they love me too.)They'll be there through thick and thin,For you must know that friendship can be true.Beauty:We don't understand the beauty inside so we criesAll the tears that fall from our eyesAnd the pain we try to hideA few know about our thoughtsAnd the scars on our body from the people who tauntWe want to stop 'this' only for some reliefBut with all the grief we feel within it's harder to stopThen it is to beginParents don't understand, And so they just shoutAnd make them feel even more worthless, And full of doubtThey tried to explain a thousand timesBut is never able to seem to findWhat will make them listen Instead of fight, So this poem is endingLet's all find an alternative from the sharp tools across our skinAnd hopefully you will noticeAll the beauty within. Memories within the Scars:We make permanent marks along our bodies with every bad memory hidden withinWe know that others do this as well, as they have sharp, and precise lines with memories within.We dont realize the beauty within us, nor do the others, they have problems much alike, and they dont know what to do.Except to drown in their sorrows, keeping the pain, anger, and sadness hidden underneath their thick hearts.We only sees ourselves as our own, we can trust nobody but ourselves.Life isnt easy, its a slide with many ups and downs, its a cakewalk full of challenges, and a cruel place where you need to work to survive, its a world of the fittest thrives.Even if it means to make permanent memories on their bodies, to remind them.But is it the best?
