Answers

Answer:

r = -20/3

Step-by-step explanation:

can i get brainliest plz

Answer:

-20/3

Step-by-step explanation:

3/4r + 2 = -3

subtract 2 on both sides...

3/4r = -5

divide by 3/4 on both sides...

3/4r divided by 3/4 is r.

-5 divided by 3/4 is the same thing as...

-5 times 4/3 (flip the fraction)

-20/3

What is the value of n in the equation
1/2(n+2)+4=3n-5

Answers

Answer:

n = 4

Step-by-step explanation:

1/2(n + 2) + 4 = 3n - 5

1/2n + 5 = 3n - 5

- 5 | - 5

1/2n = 3n - 10

- 3n | - 3n

-5/2n = -10

Which of the following transformations is an example of a non-rigid transformation?

Answers

Answer:

R to S

Step-by-step explanation:

Here, we want to get the transformation that is non-rigid

Looking at the plot, only R is facing an entirely different direction

What this mean is that by moving others across the x and y axes, we can get the transformation between them

But in the case involving R such as the transformation between R and S; merely translation is not enough

There has to be rotation and thus, in that case, it is a non-rigid transformation

Answers

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2(length + breadth)

=> 2{2x + (x + 4)) = 20

=> (2x + x + 4) = 20/2 = 10

=> 3x + 4 = 10

=> 3x = 10 - 4 = 6

=> x = 6/3 = 2

Here, according to the diagram

Length = 2x = 2(2) = 4

Breadth = x + 4 = 2+4 = 6

But breadth should always be lesser than the length. From this, it can be concluded that the actual breadth is 2x and actual length is x + 4, for perimeter to be 20.

Answer:

X is 2 I am sure

Step-by-step explanation:

2+4=6

6+6=12

2*2=4

4+4=8

12+8= 20

Step-by-step explanation:

< PRS = 123°

<QOP = x

Now

< PRS + <QRP = 180° { Being linear pair }

123° + <QRP = 180°

<QRP = 180° - 123°

< QRP = 57°

< QOP = x

= 2 * < QRP < angle at the centre is twice the angle at the circumference >

= 2 * 57°

= 114°

Therefore x = 114°

Hope it will help :)❤

Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £78.40. They share the tips in the ratio 1:3:5. How much more does Colin get over Paul?

Answers

Answer:

Share of Paul = 2/8*78.40=19.6

Share of Colin = 5/8*78.40=49

And

Share of Brian =1/8*78.40=9.8

Step-by-step explanation:

They share the tips in the ratio 2:5:1.

It means , the total share is 8 ,

that 2 out of 8 is the share of Paul

5 out of 8 is the share of Colin

And 1 out of 8 is the share of Brain

Now total tip = 78.40

Share of Paul = 2/8*78.40=19.6

Share of Colin = 5/8*78.40=49

And

Share of Brian =1/8*78.40=9.8

Please help me on math and explain how to get the answer.

Answers

Answer:

x = 128

Step-by-step explanation:

ill name the empty angle y for clarification

y + 38 + 90 = 180

y + 128 = 180

y = 52

180 - y = x

180 - 52 = x

x = 128

so here’s what i am thinking, so the right angle itself is 90°, and the top is 38°. a triangle adds up to 180° so add the 90 and 38 and then subtract it from 180. That itself gives 52°. the straight line is 180°, so you’d subtract 52° from 180° to get the outer angle, so the answer should be 128°.
