Amy because Ben spend the less money then

amy get more money

Amy has more money than her brother after all transactions.

An equation is a statement that the depicts the values of two mathematical expressions as equal using an (=) sign. Example -

2x = 5

An expression is written using individual terms (either constant or variable) separated by mathematical operations. Example -

3x + 5y + 3

We have Amy who has $1275 less than her brother ben. Ben spends $550 and Amy gets $750.

Assume that the money with Ben and Amy after transactions is $x and $y respectively. Let Ben has a initial amount of $m and Amy has of $n.

n = m - 1275

After transactions -

x = m - 550

y = m - 1275 + 750 = m - 525

Now -

m - 525 > m - 550  for every value of [m].

So, now Amy has more money.

Therefore, Amy has more money than her brother after all transactions.

Answer:

[tex] x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2} [/tex]

Step-by-step explanation:

x⁴ - 3x² + 2 = 0

x^2×2 - 3x² + 2 = 0

(x²)² - 3x² + 2 = 0

t² - 3t + 2 = 0

t = 1, t = 2

x² = 1, x² = 2

x = -1, x = 1

x = - square root 2, x = square root 2

[tex] x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2} [/tex]

Volume is the total space occupied by an object.

Answer:

x=24°

Step-by-step explanation:

(3x-6)°+x°= 90°

4x=90+6

4x= 96°

x= 24°

Answer:

Step-by-step explanation:

(3x-6)°+x°=90°

First, combine like terms:

3x°+x°-6°=90°

4x°-6°=90°

Add 6° to both sides:

4x°=96°

Divide 4 from both sides to isolate x:

x=24°

Check your answer:

3(24)-6+(24)=90°

72-6+24=90°

66+24=90°

90°=90° (correct)

Please elaborate more your question so I can actually give you a more accurate answer.

Step-by-step explanation:

Answer:

The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8

The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2

You can check your answer by plugging in your answer to the variable and making sure both side equal each other

Step-by-step explanation:

The first one: the 5 should be - from both side so you get k=-8

The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2

Remember you always want to get the variables by themselves.

Answer:

Step-by-step explanation:

12 + 0.05m = 63.80

12 + 1m/20 = 63.8

12 + m/20 = 63.8

(20 * 12)/20 + m/20 = 63.8

(20 * 12 + m)/20 = 63.8

(m + 240)/20 = 63.8

20((m + 240)/20) = 63.8

m + 240 = 20 * 63.8

m + 240 = 1276

m = 1276 - 240

m = 1036

Answer: 1 degree Fahrenheit

Step-by-step explanation:

The temperature starts at -10 degrees F, so if in two hours, the temperature has risen by 4 degrees, then the new temperature is -10 + 4 = -6 degrees F. 3 hours later, the temperature has risen another 7 degrees, so the new temperature is -6 + 7 = 1 degrees F. "addition equation" is ambiguous without knowing what class you are taking, but one such equation to represent the situation could be T = -10 + 4 + 7 = 1.

Answer:

15

Step-by-step explanation:

For 1 house, the charge just to go to a house is $12.

In each house you made $57.

$57 - $12 = $45

The charge per house just for raking was $45.

You charge $9/hour.

$45/($9/hr) = 5 hours

You shoveled 5 hours in each house.

3 * 5 hours = 15 hours

Answer: 15 hours

Answer:

[tex]y=\frac{1}{2} x-40[/tex]

Step-by-step explanation:

Slope interccept form: y=mx+b

(m= the slope, b= the y-intercept (the y value when x=0))

for every 2 x-values the y-value increases by 1. Slope is written as  [tex]\frac{rise}{run}[/tex] or  [tex]\frac{y_{1}-y_{2} }{x_{1}-x_{2}}[/tex] which is the change in the y-values divided by the change in x-values. You can find the slope by plugging in points.

[tex]\frac{(-42)-(-41)}{(-2)-(-4)} =\frac{1}{2\\}[/tex]     so now you have [tex]y=\frac{1}{2}x+b[/tex]

b is whatever the value of y is when x=0. According to the table when x=0 then y=-40. The final equation is [tex]y=\frac{1}{2} x-40[/tex]

Step-by-step explanation:

ST

3*-2 + 4*-4 = -22                3*0 + 4*5 = 20

-1*-2 + -2*-4 = 10                -1*0 + -2*5 = -10

try TS by yourself

the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

Given that,

[tex]S=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex] and [tex]T=\left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.

Now, [tex]ST=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right] \times \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]

[tex]ST=\left[\begin{array}{cc}(-6-16)&(0+20)\\(2+8)&(0-10)\end{array}\right][/tex]

[tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex]

[tex]TS= \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right]\times \left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex]

[tex]TS=\left[\begin{array}{cc}(-6-0)&(-8-0)\\(-12-5)&(-16-10)\end{array}\right][/tex]

[tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex]

Therefore, the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

Answer:

Polynomial Degree: 8 I hope this helps! : )  

Answer:

So, his normal weight is 80 kg

Step-by-step explanation:

Let his normal weight be x

If the normal weight               increasing percent         now weighs

       100                                               10                                 110

         x                                                  10                                88

Now we can get a equation as,

[tex]100 = 110\\x = 88[/tex]

We can write this as a fraction

[tex]\frac{100}{x} = \frac{110}{88}[/tex]

You can use cross multiplication to solve this

[tex]88*100=110x\\8800=110x\\\frac{8800}{110} =\frac{110x}{110} \\80kg = x[/tex]

Hope this helps you.
