X-5y=5 3x+y=31 solve the system

Let her daily allowance be RMy.

0.25y x 14 = 28

0.25y=2

y=8

Therefore, her daily allowance is RM8.

Answer:

[tex]x=8[/tex]

Step-by-step explanation: [tex]25[/tex]%[tex]\times14\times[/tex][tex]x=28[/tex]

Solve the equation

[tex]0.25\times14x=28[/tex]

Multiply the monomials

[tex]3.5x=28[/tex]

Divide both sides of the equation by the coefficient of variable

[tex]x=\frac{28}{3.5}[/tex]

Multiply both the numerator and denominator with the same integer

Solve the whole numbers

92 - 43 = 49

Solve the fractions using LCD

8/9 - 5/6 = 1/18

Polynomials are expressions. The factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In order to factorize the given polynomial, we need to take the common terms out of the polynomial. Therefore, the polynomial can be written as

[tex]5x^4 - 80\\\\[/tex]

If we look at the polynomial the common term 5 can be taken out from both the terms, therefore,

[tex]5x^4 - 80\\\\= 5(x^4-16)[/tex]

Hence, the factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).

Answer:

34

Step-by-step explanation:

Answer: 30° and 110°

55° and 85°

70° and 70°

The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:

= 180° - 40°

= 140°

Therefore,

30° + 110° = 140°

55° + 85° = 140°

70° + 70° = 140°

Step-by-step explanation:

Answer:

Let's set up an equation;

12/100 * x = 16.5

where 12/100 is 12%

x is the number of the 12%

that would equal 16.5

So solve for x;

12/100 * x = 16.5

12/100x = 16.5

0.12x = 16.5

Answer:

Kayla

Step-by-step explanation:

To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework

Kayla: 3.2 ÷ 4 = 0.8

Karen: 5 ÷ 6 = 0.833

Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

Answer:

$115.83

Step-by-step explanation:

$120 * 1.0725 = Amount including Sales Tax

= $128.70

Discount of 10% =

$128.70 * 90%

= 115.83

The system of equations for this problem is defined as follows:

From the first equation, we have that:

y = 21 - 3x.

The second equation is given as follows:

2x + 2y = 24.

Simplifying the equation, we have that:

x + y = 12.

Replacing the first equation, we have that the value of x is obtained as follows:

x + 21 - 3x = 12

2x = 9

x = 4.5.

Then the value of y is of:

4.5 + y = 12

y = 7.5.

x = e^12/100

Step-by-step explanation:

Solve for x over the real numbers:

10 ln(100 x) - 3 = 117

Add 3 to both sides:

10 ln(100 x) = 120

Divide both sides by 10:

ln(100 x) = 12

Cancel logarithms by taking exp of both sides:

100 x = e^12

Divide both sides by 100:

Answer:  x = e^12/100

Answer:

8 hours

Step-by-step explanation:

First, you must subtract $32 from $125. You end up with $93.

Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.

96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.

The solution is Option B.

The two right scalene triangles can be formed from the parallelogram B

A scalene triangle is a type of triangle with three different length sides and three interior angles that add up to 180 degrees. Scalene triangles have no equal of parallel sides , hence there is no line of symmetry. The interior angles of a scalene triangle can be acute , right or obtuse angles.

Given data ,

Let the parallelogram be represented as ABCD

Now , the figure ABCD represents a rectangle

So , the measures of angles ∠ABC = measure of angle ∠DCB = 90°

Let the diagonal of the rectangle be AC

The base of the rectangle = BC

The height of the rectangle = AB

So , the diagonal cuts the rectangle into two triangles each having different lengths and angles

And , the two triangles are ΔABC and ΔADC

Now , the triangles ΔABC and ΔADC are right scalene triangles

Hence , the triangles are scalene triangles
