Answer:
Find the value of x(attachment 11)
6)
7x = 6 + 5x
7x - 5x = 6
2x = 6
x = 6/2 = 3
7)
30 = 4x + 6
4x = 30 - 6 = 24
x = 24/4 = 6
8)
2(x + 4) =16
x + 4 = 16/2 = 8
x = 8 - 4 = 4
9)
7 + 5x = 3x + 13
5x - 3x = 13 - 7
2x = 6
x = 6
Find the area(From attachment 2)
1) Area = 4* 5 = 20
2)Area = 7 * m = 7m
3). Area = 3* a = 3a
4). Area = x*x = x²
5). Area = 4*x + 3* 4 = 4x + 12
6). Area = 7*a + 7*9 = 7a + 63
7). Area = 3x*x + 2*3x = 3x² + 6x
expression of line segment
8) x + 9
9). x + 4
10). a + 2
Answer to Q6:
x = 3
Step-by-step explanation:
Given equation is :
7x = 6+5x
We have to find the value of x by simplifying above equation.
Adding -5x to both sides of above equation, we get
7x-5x = 6+5x-5x
Adding like terms, we have
2x = 6+0
2x = 6
Dividing by 2 to both sides of above equation, we get
2x/2 = 6/2
x = 3 Which is the answer.
Answer to Q7:
x = 6
Step-by-step explanation:
We have given an equation.
30 = 4x+6
We have to find the value of x.
Adding -6 to both sides of above equation , we get
30-6 = 4x+6-6
24 = 4x+0
24 = 4x
Dividing by 4 to both sides of equation, we have
24/4 = 4x/4
6 = x
Swapping equation , we have
x = 6 which is the answer.
Answer to Q8:
x = 4
Step-by-step explanation:
Given equation is:
2(x+4) = 16
We have to find the value of x by simplifying it.
Distributing 2 to parentheses of above equation, we get
2x+8 = 16
adding -8 to both sides of above equation, we have
2x+8-8 = 16-8
2x+0 = 8
2x = 8
dividing by 2 to both sides of above equation, we have
2x/2 = 8/2
x = 4 which is the answer.
Answer to Q8:
x = 3
Step-by-step explanation:
We have given following equation.
7+5x = 3x+13
We have to find the value of x by simplifying above equation.
Adding -3x to both sides of above equation, we get
7+5x-3x = 3x+13-3x
adding like terms, we get
7+2x = 13
adding -7 to both sides of above equation, we get
-7+7+2x = -7+13
2x = 6
dividing by 2 to both sides of above equation , we have
2x/2 = 6/2
x = 3 which is the answer.
