Answer quickly I'll give brainliest <br><br>3(x+2)-(2x-7)&lt;(5x-1)-2(x+6)​​
aivan3 [116]

Answer:

x=+5

Step-by-step explanation:

3(x+2)-2x-7=-(-5x-1)-2(x+6)

We move all terms to the left:

3(x+2)-2x-7-(-(-5x-1)-2(x+6))=0

We add all the numbers together, and all the variables

-2x+3(x+2)-(-(-5x-1)-2(x+6))-7=0

We multiply parentheses

-2x+3x-(-(-5x-1)-2(x+6))+6-7=0

We calculate terms in parentheses: -(-(-5x-1)-2(x+6)), so:

-(-5x-1)-2(x+6)

We multiply parentheses

-(-5x-1)-2x-12

We get rid of parentheses

5x-2x+1-12

We add all the numbers together, and all the variables

3x-11

Back to the equation:

-(3x-11)

We add all the numbers together, and all the variables

x-(3x-11)-1=0

We get rid of parentheses

x-3x+11-1=0

We add all the numbers together, and all the variables

-2x+10=0

We move all terms containing x to the left, all other terms to the right

-2x=-10

x=-10/-2

x=+5

Pls help thanks ! it’s math !
likoan [24]

Answer:

a. (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16

b. (8 × 2) = (2 × 8) = (8 + 8 ) = 16 {Using the commutative property}

c. It is easier to calculate (8 + 8 ) than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2).

Step-by-step explanation:

Multiplication operation is equivalent to the repeated addition operation.

For example (3 × 4) can be treated as 3 groups of 4 or 4 + 4 + 4 then use the addition facts to learn the multiplication facts.

a. Now, (8 × 2) can be treated as 8 groups of 2 or 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 then using the addition facts we get (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16

b. If we apply the commutative property of multiplication then (8 × 2) = (2 × 8) and we can assume it as 2 groups of 8 or (8 + 8) i.e. 16 which makes it easier to get the multiplication process by addition operation.

c. It is clear that (8 + 8) is much more easier to calculate than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) by addition operation. (Answer)

A parking space shaped like a parallelogram has a base of 17 feet and a height of 9 feet if a mini car 6 feet long and five feet
lesantik [10]

Answer:

123 cm²

Step-by-step explanation:

First of all, we need to know how exactly to find the area of a parallelogram.

<u>Area</u><u> </u><u>of</u><u> </u><u>parallelogram</u><u>=</u><u> </u><u>Base</u><u>*</u><u>Height</u>

PARALLELOGRAM-

BASE= 17 ft

HEIGHT= 9ft

AREA= 17*9= 153 cm²

The area of parallelogram, will be considered as WHOLE AREA.

Now,

AREA OF MINI CAR-

length= 6 ft

Width= 5 ft

Area= 6*5= 30 ft ²

Square feet uncovere-

153 ft²- 30 ft²= 123 ft²
