30-10x and 10(3-x) equivalent or not?

Mathematics
1 answer:
BARSIC [14]3 years ago
3 0

Answer:

no

Step-by-step explanation: You can use variables to find that out. PEMDAS works too (parenthesis, exponents, multiplication, division, addition, subtraction). Put a random number for x and then you can see that it is not equivalent. Example: 30 - 10x7 = 40 but 10 (30-70) = -400

Elanso [62]

Answer:

12.8mph

Step-by-step explanation:

Let 'w' represent her walking speed

->if her jogging speed is 8mph faster than her walking speed

Jogging speed=  w+8

Using the time equation i.e time = dist/speed

For walking when distance is 8miles

time = dist / speed= 8/w hrs

For jogging when distance is 13miles

time = dist / speed= 13/(w+8) hrs

Equating the time

jog time = walk time

13/(w+8) = 8/w

By cross multiplying it

13w = 8w + 64

5w = 64

w=64/5

w=12.8mph

Therefore, 12.8mph is her walking speed.

Maksim231197 [3]

Given:

The equation is:

x(4+5)=54

To find:

The next step in simplifying the equation by using distributive property.

Solution:

Distributive property: According to this property if a, b and c are three real numbers, then

a(b+c)=ab+ac

We have,

x(4+5)=54

Using the distributive property, we get

x(4)+x(5)=54

It can be written as:

4x+5x=54

Therefore, the next step of the simplification is 4x+5x=54.
