Solve for x 2(x-7)=0.2(x+2)+5.11

Mathematics
1 answer:
Kryger [21]3 years ago
3 0

Answer:

Step-by-step explanation:

You start off by rewriting the equation:

2(x-7)=0.2(x+2)+5.11\\

Then you have to factor:

2x-14=0.2x+0.4+5.11

Then you subtract the 0.2x:

1.8x-14=0.4+5.11

Add the positives on the right:

1.8x-14=5.51

Add 14:

1.8x=19.51

Divide:

x=10.84

You get x is approximately equal to 10.84

Answer:

A.  6 and 30

B.  8 and 28

Step-by-step explanation:

we know that the area of the three squares must satisfy the Pythagorean Theorem so c² = a² + b²

where

c²  is the area of the largest square

a² and b² are the areas of the smaller squares

now.. 36² = a² + b2

The sum of the areas of the smaller squares must be equal to 36

therefore

6 and 30 >>>> could be the areas of the smaller squares (6 + 30 = 36)

8 and 28 >>>> could be the areas of the smaller squares (8 + 28 = 36)

hope it clears your mind.

Please mark as the brainliest

42 liters of juice were evenly
I am Lyosha [343]

Answer: 42/6=7

Step-by-step explanation:

there's 42 liters of juice right? so to <u>divide</u> it into six batches all you got to do is divide all the liters of juice into how many batches you need. So as it says in the question, just divide 42 by 6 and you'll get your answer which is 7.

Two angles of a triangle are 47 and 32 degrees. Select all angles that could represent exterior angles of a triangle.
notsponge [240]

Answer:

133, 79, 148 are ALL possible, so select 133 and 79

Step-by-step explanation:

Subtract 47 and 32 from 180 to find the third angle of the triangle (it is 101).

Then do 180-101 = 79

180-32=148

180-47=133

That tells you the exterior angle of each. Only two possible choices on your list.
