5) 4cm x 4cm = 16cm; then 16 / 2 = 8 to get the triangle on top
answer- 24cm
6) 6m x 2m = 12m; 8m x 2m = 16m; then add it together
answer- 28m
7) 9 x 8 = 72; 4 x 2 = 8 (this will equal the little triangles); 72-8
answer- 64ft
8) 5 x 12 = 60 - 24
answer- 36in
9) (4 x 4) + (6 x 8)
answer- 64ft
hope this helps :D
Answer:
a) one solution(x = 9)
b) no solution
c) infinite solutions
Step-by-step explanation:
a) To solve this equation, we can add 4 on both sides in order to isolate x:
x - 4 =5
+ 4 + 4
x = 9
Since x equals 9, that counts as only one solution, as there is only one value of x that makes the equation true.
b) We start by subtracting 2x from both sides to combine the variable terms:
2x - 6 = 2x + 5
-2x -2x
-6 = 5
The statement, -6 = 5 is never true and it is not dependent on the value of x. This means there are no solutions to this equation.
c) We can start by subtracting 3x from both sides to combine the terms with x:
3x + 12 = 3x + 12
-3x -3x
12 = 12
The statement above is always true, and no matter the value of x, it will always be true. This means there are infinite solutions to the equation.
25/25 is equal to 1 whole. 3/4 x 1 is 3/4
3/4=?/100 : to get from 4 to 100 you x by 25. you then have to multiply 25 by 3 which gives you 75 which makes it 75/100 which can be simplified into 3/4
Rearrange equation to get
6x>12 so
x>2
