4x - x - 1) < 5x - 7

3x - 5x < -7 + 1

-2x < -6

2x > 6

x > 3

Answer:

See below :)

Step-by-step explanation:

We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3

[tex]\frac{6}{\sqrt3}[/tex]

We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3

[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]

This then makes it 6 times root 3 over 3

[tex]\frac{6\sqrt3}{3}[/tex]

We then get [tex]2\sqrt{3}[/tex]

Answer:

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

Hope this helps!

The value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that x is a non-negative number, a student conjectured that x + 3 < x².

Since x is a non-negative number, A and B are eliminated.

This leaves C and D at the value of x = 2,

2 + 3 < 2²

5 < 4 is false.

Therefore, the value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.

Answer:

4/3

Step-by-step explanation:

Answer:

well the answer is 45/20  it would be greater than

Step-by-step explanation:

Using proportions, the amount of acres that each children will be is given by:

9 and 4/5 acres.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For this problem 49 acres will be split evenly across 5 children, hence the amount that each will get is:

A = 49/5.

The quotient of 49 and 5 is of 9 with a remainder of 4, hence as a mixed number, the amount is:

9 and 4/5 acres.

Answer:

[tex]\dfrac{1}{2}x-10=-13[/tex]

Step-by-step explanation:

Let x be the unknown number.

Given:

Therefore, the equation is:

[tex]\boxed{\dfrac{1}{2}x-10=-13}[/tex]

Solving for x

To solve, add 10 to both sides:

[tex]\implies \dfrac{1}{2}x-10+10=-13+10[/tex]

[tex]\implies \dfrac{1}{2}x=-3[/tex]

Multiply both sides by 2:

[tex]\implies 2 \cdot \dfrac{1}{2}x=2 \cdot -3[/tex]

[tex]\implies x=-6[/tex]

Equation :-

→ (1/2)x - 10 = -13

Solution :-

→ x = -6

Step-by-step explanation:

The equation will be,

→ (1/2)x - 10 = -13

Now the required value of x will be,

→ (1/2)x - 10 = -13

→ (1/2)x = -13 + 10

→ x = -3 × 2

→ [ x = -6 ]

Hence, the value of x is -6.

Answer:

385 cards

Step-by-step explanation:

First, find 40% and 25% of 1100.

2/5 * 1100

2200/5 = 440 cards dated before 1970

1/4 * 1100

1100/4 = 275 cards dated between 1970 and 2000

Then add the two amounts together.

440 + 275 = 715 cards between pre-1970 and 2000

After that, subtract your new sum from 1100.

1100 - 715 = 385 cards after 2000

(Or to make it easier, just find 35% of 1100.)

Answer: 82:73

Step-by-step explanation:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2. Do you see that these ratios both represent the same comparison?

Step-by-step explanation:

When the non-refundable fee increases to $15, the y-intercept is also increased to 15. The graph are parallel to each other but only touches the y-axis at 10 and 15 respectively

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.

Linear equations are generally represented in the form

y = mx + c

The y-intercept is the point at which the graph touches the y - axis

In the question, we are given an equation f(h) = 8h + 10

The slope and y - intercept here are 8 and 10 respectively.

However, when the non-refundable deposit is increased to 15, the y - intercept is increase by 5 units to becomes 15.

The value of k is proved to be -8

The equation is given as

-4k + 2(5k - 6) = 3k - 36

Open the bracket in the above equation

So, we have

-4k + 10k - 12 = 3k - 36

Collect the like terms in the above equation

So, we have

-4k + 10k - 3k = 12 - 36

Evaluate the like terms in the above equation

So, we have

3k = -24

Divide both sides of the above equation by 3

So, we have

k = -8

Hence, the value of k is proved to be -8
