Simplify:
3(x - 1) = 8x -3
Expand:
3x - 3 = 8x - 3
Cancel -3:
3x = 8x
Move all terms to one side:
3x - 8x = 0
Simplify 3x - 8 to -5x
-5x = 0
Divide both sides by -5:
x = 0
Answer:
7
Step-by-step explanation:
Because decagon has 10 sides. If the perimeter is 70, I would divide it. 70/10 = 7
Pardon me if I turn out to be wrong, but that is how I think you would solve this.
Answer:
x = 12 , y = 60
Step-by-step explanation:
The figure has 2 pairs of parallel sides and is therefore a parallelogram.
The opposite sides and opposite angles are congruent , then
x + 3 = 15 ( subtract 3 from both sides )
x = 12
and y = 60
Answer:
The statement ' the population of Groverdale is greater than the population of Tittlehook ' by Alaina is CORRECT.
Step-by-step explanation:
The population of Groverdale = 553,000.
The population of Tittlehook = 535,841.
Now, the difference in the population of two sates is
= The population of Groverdale - The population of Tittlehook
= 553,000 - 535,841
= 17, 159
⇒The population of Groverdale - The population of Tittlehook = 17, 159
Now, according to the arithmetic rules:
If there area two given terms say A and B .
Also, A - B = x
Then A > B if the difference x is positive.
and A < B if the difference x is negative.
Here the difference of the population = 17, 159 > 0
⇒The population of Groverdale > The population of Tittlehook
Hence, the statement ' the population of Groverdale is greater than the population of Tittlehook ' by Alaina is CORRECT.
Answer:
Width is 15, length is 35.We can check our answer by multiplying the length by 2 and the width by two in order for the perimeter to be equal to 200.15 times 2 is 30 and 35 times two equals 70.70+30=100 so our solution satisfies our problem.
Step-by-step explanation:
Let the width be x.Then the length should be x+20.The farmer can’t use more than 100 ft of fencing and by mentioning enclosing a rectangle area for a pigpen, we can tell that 100 is the perimeter.So 2(x+20) + 2(x)=100.2x+ 40 + 2x=100.4x+40=100.4x=60.X is 15 which is the width so then the length is 35.
