Answer:

gfxdg

Step-by-step explanation:

Answer:

a × 2 means 'a' multiplied by 2

a(2) also means 'a' multiplied by 2

So both mean the same.

a × 2 means 2 times the value of variable "a".

a(2) represents a function "a" with input 2.

a × 2 means the value of variable "a" multiplied by 2. In mathematical terms, it is simply "2 times a" or "2 * a."

a(2) indicates a function notation, where "a" is a function and "2" is the input to that function.

It is not multiplication but rather a way of representing the value of the function "a" when the input is 2.

Hence, a × 2 means 2 times the value of variable "a".

a(2) represents a function "a" with input 2.

Answer:  Choice A.

- 4.5 because it is the negative number with the greatest absolute value.

===================================================

Explanation:

Stuff to the left is smaller than stuff on the right for any number line.

For example, we can say 2 < 5 since 2 is to the left of 5.

Another example: -7 < 4

To find the smallest item of your given list, we need to look at the value that is furthest to the left. That value would be -4.5 and this value is negative with the largest absolute value (i.e. it is furthest away from 0).

Check out the number line diagram below. It shows where all of the values are placed. We can see that -4.5 is the left-most item.

Step-by-step explanation:

Answer:

0.67

Step-by-step explanation:

4/6 = 0.66666667

The 6 in the thousandth place is greater than 5, therefore we add 1 to the 6 that's in the hundredth place.

Answer:

C. 8/17

Step-by-step explanation:

PM = 16+14 = 30 cm

KP= LN = 16×tan45° = 16×1 = 16cm

by using pythagorean theorem, we find :

KM² = PM²+KP²

= 30²+16²

= 900+256

= 1156

=> KM =√1156 = 34cm

so, cos theta = KP/KM = 16/34 = 8/17

Answer:

128 : 192 : 240

Step-by-step explanation:

Given that

A : B = 2 : 3

That is B = 1.5A

Then in fractional form

[tex]\frac{B}{C}[/tex] = [tex]\frac{4}{5}[/tex] , so

[tex]\frac{1.5A}{C}[/tex] = [tex]\frac{4}{5}[/tex] ( cross- multiply )

4C = 7.5A ( divide both sides by 4 )

C = 1.875A = 1.875 × 2 = 3.75

The ratios of A : B : C = 2 : 3 : 3.75

Sum the parts of the ratio , 2 + 3 + 3.75 = 8.75

Divide the quantity by 8.75 to find the value of one part of the ratio

560 ÷ 8.75 = 64 , then

2 parts = 2 × 64 = 128

3 parts = 3 × 64 = 192

3.75 parts = 3.75 × 64 = 240

Then A : B : C = 128 : 192 : 240

Answer:

[tex]x = \frac{5}{12} [/tex]

Step-by-step explanation:

[tex] \frac{3}{2x} - \frac{2}{3x} [/tex]

➡️ [tex] \frac{3}{2x} - \frac{2}{3x} = 2[/tex]

➡️ [tex] \frac{5}{6x} = 2[/tex]

➡️ [tex]5 = 12x = 12x = 5[/tex]

➡️ [tex]x = \frac{5}{12} [/tex]

Answer:

x = [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{2}[/tex] x - [tex]\frac{2}{3}[/tex] x = 2 ( multiply through by 6 to clear the fractions )

9x - 4x = 12

5x = 12 ( divide both sides by 5 )

x = [tex]\frac{12}{5}[/tex]

Answer:

∠YDC measures 140°.

Step-by-step explanation:

We can consider using the Exterior Angle Theorem. According to the theorem, the exterior angle of a triangle is equal to the two opposite interior angles.

In other words:

[tex]\displaystyle m \angle YDC = m\angle DCB + m\angle CBD[/tex]

Substitute:

[tex]\displaystyle (15x + 5) = (80) + (6x+6)[/tex]

Solve for x. Combine like terms:

[tex]15x + 5 = 6x + 86[/tex]

Simplify:

[tex]9x = 81[/tex]

And divide. Hence, the value of x is:

[tex]x = 9[/tex]

∠YDC is given by:

[tex]\displaystyle m\angle YDC = 15x + 5[/tex]

Since we now know the value of x, substitute and evaluate:

[tex]\displaystyle \begin{aligned} m\angle YDC &= 15x + 5 \\ &= 15(9) + 5 \\ &= 135 + 5 \\ &= 140^\circ\end{aligned}[/tex]

In conclusion, ∠YDC measures 140°.

Answer:

    8- 3x = 2 I think this is

Answer: The unknown number is 2.

Step-by-step explanation:

Let the number be x

8-3x = 2

or, -3x = -6

so, x = -6/-3

so, x = 2

Step-by-step explanation:

open the bracket

6={(1/5×4y) + 1/5×10}

6=4/5y+2

6-2=4/5y

4=4/5y

divide both sides by 4/5

y=1/5

The answer you are looking for is y=5.

Solution/Explanation:

Writing out the problem,

6=1/5(4y+10)

Using the Distributive Property,

6=4/5y+2

Subtracting 2 from both sides of the equation,

6-2=4/5y

4=4/5y

Multiplying both sides by 5, to transform the fraction into a whole number,

20=4y

Finally, dividing both sides by 4,

So, therefore the final answer is y=5.
