Answer:

5j+10

Step-by-step explanation:

In this question, you cannot find the answer to j, so you would just be simplifying the equation. So you would break the equation up into different parts and put the like parts together. So that it would be: (2j+3j)+(5+5)

5+5=10. So the answer is: 5j+10

Answer:

y=1.8

Step-by-step explanation:

first change the fraction into a decimal.

4/5 =0.8

plus the 0.8 to both sides

y=1.8

Answer:

[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

Answer:

10)

180-3x =x (corresponding angles are equal)

x=45°

11)180-5x=3x ( same reason)

x=10°

12)180-6x=3x(same reason)

x=20°

Answer: See explanation

Step-by-step explanation:

10) Same side interior angles add up to 180°

3x + x = 180

4x = 180

x = 45

11) Same side interior angles add up to 180°

5x + 3x = 180

8x = 180

x = 22.5

12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well

6x + 3x = 180

9x = 180

x = 20

Step-by-step explanation:

We need to find the value of the given expression :

[tex]5^{\dfrac{5}{2}}\times 20^{\dfrac{3}{2}}\div 10^{-2}[/tex]

We can do it as per BODMAS rule.

[tex]5^{\dfrac{5}{2}}\times (\dfrac{20^{\dfrac{3}{2}}}{10^{-2}})\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times {10^{2}}\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5\times 4)^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5^{\dfrac{3}{2}})\times (4)^{\dfrac{3}{2}}}\times 100\\\\=5^{(\dfrac{5}{2}+\dfrac{3}{2})}\times 2^2^{\dfrac{3}{2}}\times 100\\\\=5^4\times 2^3\times 100\\\\=625\times 8\times 100\\\\=500000[/tex]

So, the required answer is 500000.

Step-by-step explanation:

If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong

3 * 9 = exactly 27

However, for approximation sake ;

We could round 9 to 10 ; and multiply 10 by 3

10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;

3 * 9 = exactly 27 or approximately 30

Answer:

dang, if i had to guess, just add your numbers then divide.

Step-by-step explanation:

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

Explanation:

In a parallelogram, there are only two sizes of angle - two are acute and two are obtuse.

Opposite angles are equal .

Consecutive angles are supplementary because they are co-interior angle on parallel lines.

An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.

Let one angle be  

x

The size of the other angle is given by  

9

x

−

30

2

x

+

(

x

=

x

20

x

=

420

x

=

21

°

The obtuse angles are each  

180

−

21

=

159

°

The other option where the given angle is the opposite angle is described is well explained by Alan P.

Step-by-step explanation:

The interior angles of the parallelogram are 21° and 159° respectively.

What is parallelogram?

A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.

In a parallelogram opposite interior angles are equal and the angles on the same side of the traversal are supplementary (i.e) 180°

For the given situation,

The measure of one interior angle be [tex]x[/tex] and

Another angle was given as [tex]9x-30[/tex]°  

⇒[tex]x+9x-30[/tex]°[tex]=180[/tex]°

⇒[tex]10x=180[/tex]°[tex]+30[/tex]°

⇒[tex]10x=210[/tex]°

On dividing [tex]10[/tex] on both sides,

⇒[tex]\frac{10x}{10}=\frac{210}{10}[/tex]

⇒[tex]x=21[/tex]°

So, another angle is [tex]9x-30[/tex] = [tex]9[/tex]×[tex]21-30[/tex]

⇒[tex]189-30[/tex]

⇒[tex]159[/tex]°

Hence we can conclude that the interior angles of the parallelogram are 21° and 159°.
