 x=8y-12   (ii)

 2. Let's substitute the equation (ii) into the equation (i):

 x+12y=68
 (8y-12)+12y=68

 3. Then, you have:

 8y-12+12y=68

 4. When you clear "y", you have:

 20y-12=68
 20y=68+12
 20y=80
 y=80/20
 y=4

 5. You already have the value of "y". Now, you must substitute this value into the equation (ii):

What is 5/15 written as a decimal???

What is 4/15 written as a decimal???

What is 3/15 written as a decimal???

Answers

the first when you do is divide 15 by 5 and you get 3 so. 0.333333 number 2 is 0.26666 the 3rd is 1 divided by 5 equals 0.2
Hello!

There are a couple ways we can use to convert a fraction to a decimal, but let's stick with the easiest one.

To convert a fraction to a decimal, simply divide the numerator (top part of the fraction) by the denominator (bottom part).

The first fraction is 5/15. Its numerator is 5, and its denominator is 15. Divide the top by the bottom.

5 ÷ 15 = 0.3333333333

Because this decimal keeps repeating, it is called a "repeating fraction."

We don't want to write all those 3's over and over again, so to indicate that it is a repeating decimal, simply put a bar above the 3.

Convert the other two fractions using the same method:

4 ÷ 15 = 0.266666667

Remember to put a bar above the repeating number.

3 ÷ 15 = 0.2

Since this decimal does not repeat, it is called a "terminating decimal". You do not have to put a bar above the 2.

Don't forget this method!

Why is it most logical to let x represent Dianna’s current age?

Answers

let's say Diana is "x" years old today.

in 3 years, she's going to be " x + 3 " years old.

33 years ago, she was " x - 33 " old.

how much is 4 times that anyway?  well 4(x-33), that's 4 times as 33 years ago her age.

now, we know in 3 years, x+3, she'll be "4 times as old as she was 33 years ago", 4(x-33), therefore, those amounts are equal then,

[tex]\bf \stackrel{\textit{3 years from now}}{x+3}~~=~~\stackrel{\textit{4 times as old as she was 33 years ago}}{4(x-33)} \\\\\\ x+3=4x-132\implies 135=3x\implies \cfrac{135}{3}=x\implies 45=x[/tex]

why is it most logical to use "x" for her age today?

well, because 3 years from now is just x + 3
and
33 years ago is x - 33, 4 times that is 4( x - 33 ).

works very well as a point of reference.

Answer: Jiren is too strong. (congruent triangles)

Answers

The answer to this question is A)Congruent Triangles.

Hope I helped you :D

Answer:

Option: A is correct (congruent triangles)

Step-by-step explanation:

To prove that he diagonals of a parallelogram bisect each other we have to go through the following steps:

Angle DBA is congruent to angle BDC. Angle CMD is congruent to angle AMB. Triangle CMD is congruent to triangle AMB. Segment AM is congruent to segment MC. M is the midpoint of segment AC. Segment BD bisects segment AC. Segment BM is congruent to segment MD. M is the midpoint of segment BD. Segment AC bisects segment BD.

Hence we have to use the concept of congruent triangles in order to prove that the diagonals of a parallelogram bisect each other.

Hence, option A is correct

How many groups will be created, for instance, if 30 students need to be separated into groups of five for a sporting event? The division operation can be used to quickly and easily fix such issues. In this case, we must divide 30 by 5.

given:

8 digits written in that same order ( 8,7,6,5,4,3,2,1 ) over and over again

So, we have to find 5479th digit

= 5479/8

= 684 7/8

Now, The 684 quotient tells us how many complete times the sequence goes through the cycle of  8,7,6,5,4,3,2,1, and the 7 remainder tells us which member of the cycle is the 5479 digit.

Since the 7th member of the cycle is 2.

Hence, the 5479th digit is 2.

How can Brady use fraction strips to show that 3 4 and 7 8 are NOT equivalent?

Answers

Brady needs three strips that each represent one fourth (1/4). He needs to line them up end to end. The new long strip he has created represents 3/4.

Next Brady needs seven strips that each represent one eighth (1/8). He needs to line them up end to end. The new long strip he has created represents 7/8.

If the two long strips he created were equal then 3/4 would equal 7/8 but as they are not equal this is not the case. Since the strip for 7/8 is longer, the fraction 7/8 is greater than 3/4.
Final answer:

To demonstrate that 3/4 and 7/8 are not equivalent, Brady can use fraction strips to visually compare the colored portions of the strips, which will clearly show that 7/8 is greater than 3/4 as it has more colored sections.

Explanation:

To show that 3/4 and 7/8 are not equivalent using fraction strips, Brady can follow these steps:

Take one strip and divide it into four equal parts to represent the fraction 3/4. Color three of these parts.Take another strip, divide it into eight equal parts to represent the fraction 7/8, and color seven of these parts.Compare the two colored strips side by side.

Brady will observe that the strip representing 7/8 has more colored sections than the strip representing 3/4, even though the strips are the same length. This visual comparison confirms that 3/4 is less than 7/8, thus they are not equivalent fractions. The fraction 7/8 is only one-eighth away from being a whole, whereas 3/4 is one-fourth away.

Find a second-degree polynomial p such that p(1) = 5, p'(1) = 7, and p''(1) = 10.

Answers

When p(x) = ax^2 +bx +c
p'(x) = 2ax +b
p''(x) = 2a

You require
.. 2a = 10
.. 2a +b = 7
.. a + b + c = 5

Thus a=5, b=-3, c=3, and
.. p(x) = 5x^2 -3x +3
Final answer:

The given conditions suggest a second-degree polynomial of form p(x) = ax^2 + bx + c. By solving the given conditions a = 5, b = -3, and c = 3, yielding the polynomial p(x) = 5x^2 - 3x + 3.

Explanation:

The question is asking for a second-degree polynomial, which can generally be written in the form p(x) = ax^2 + bx + c. Given that p(1) = 5, that means a + b + c = 5. The derivative of p(x), p'(x) = 2ax + b, and p'(1) = 7, so 2a + b = 7. The second derivative, p''(x) = 2a, and p''(1) = 10, so 2a = 10 or a = 5. We can substitute a = 5 into the first two equations to find the values of b and c. So, b = -3 and c = 3. Therefore, the original function is p(x) = 5x^2 - 3x + 3.

 4x+1 = 25
    4x = 24
      x = 6

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

We have been given a triangle and we are asked to solve for x using angle bisector theorem.

Angle bisector theorem states that if a ray bisects an angle of a triangle, then it divides the opposite side of triangle into segments that are proportional to the other two sides.

Using angle bisector theorem we can set an equation as:

[tex]\frac{4x+1}{5}=\frac{15}{3}[/tex]

Let us solve for x by multiplying both sides of our equation by 5.

[tex]\frac{4x+1}{5}*5=\frac{15}{3}*5[/tex]

[tex]4x+1=5*5[/tex]

[tex]4x+1=25[/tex]

Let us subtract 1 form both sides of our equation.

[tex]4x+1-1=25-1[/tex]

[tex]4x=24[/tex]

Upon dividing both sides of our equation by 4 we will get,

[tex]\frac{4x}{4}=\frac{24}{4}[/tex]

[tex]x=6[/tex]

Therefore, the value of x is 6 units.

Do 1.5 cm, 3 cm, 1.5 cm make a triangle and what kind

Answers

Don't really know how to explain making one but the triangle will be a isosceles for sure. 

The lengths 1.5 cm, 3 cm, and 1.5 cm cannot form a triangle because the sum of the lengths of the two shorter sides is equal to the length of the longest side, which does not satisfy the Triangle Inequality Theorem.

The question asks if lengths 1.5 cm, 3 cm, and 1.5 cm can form a triangle, and if so, what kind of triangle it would be. To determine whether these lengths can form a triangle, we use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For these lengths:

1.5 cm + 1.5 cm = 3 cm1.5 cm + 3 cm > 1.5 cm1.5 cm + 3 cm > 1.5 cm

We see that when we add the lengths of the two shorter sides (1.5 cm + 1.5 cm), it equals the length of the longest side (3 cm). According to the Triangle Inequality Theorem, the lengths do not meet the condition for forming a triangle because the sum must be greater than, not equal to, the length of the third side. Therefore, these lengths cannot form a triangle.

The idea is to go through each answer choice and see if that value is in the range. To do so, draw a horizontal line from that value at the y axis and see if it crosses the graph.

So for example, for choice A, we draw a horizontal line through -2 on the y axis. You'll see that the horizontal line crosses the green part of the piecewise function graph. So y = -2 is in the range. Similar situations will happen for B and C as well. 

The only time that this doesn't happen is when y = 5. Draw a horizontal line through 5 on the y axis. This horizontal line is too high to cross through any part of the piecewise function. So y = 5 is not in the range.
