Answer:
(1/2)x+(1/4)=x
x=0.5
3x+3=2(x+7)
x=11
2(x-5)+7=x+8
x=11
0.8x+5=0.2(40-x)
x=3
5(x-1)-6x=-11x
x=0.5
6(x+2)-x=4(x+4)+7
x=11
(1/2)(x+8)+(3/2)x=10
x=3
Step-by-step explanation:
(1/2)x+(1/4)=x
x-0.5x=0.25
0.5x=0.25
x=0.5
3x+3=2(x+7)
3x+3=2x+14
3x-2x=14-3
x=11
2(x-5)+7=x+8
2x-10+7=x+8
2x-x=8+10-7
x=11
0.8x+5=0.2(40-x)
0.8x+5=8-0.2x
0.8x+0.2x=8-5
x=3
5(x-1)-6x=-11x
5x-5-6x=-11x
11x-x=5
10x=5
x=0.5
6(x+2)-x=4(x+4)+7
6x+12-x=4x+16+7
6x-4x-x=16+7-12
x=11
(1/2)(x+8)+(3/2)x=10
0.5x+4+1.5x=10
2x=6
x=3
Answer:
The sequence is geometric
The common ratio is 0.5
Step-by-step explanation:
In the arithmetic sequence, there is a common difference between each two consecutive terms
In the geometric sequence, there is a common ratio between each two consecutive terms
Let us check the given sequence
∵ The first 3 terms are 12, 6, 3
∵ 6 - 12 = -6
∵ 3 - 6 = -3
∵ There is no common difference between the consecutive terms
∴ The sequence is not an arithmetic sequence
∵ 6 ÷ 12 = 0.5
∵ 3 ÷ 6 = 0.5
∴ There is a common ratio between each two consecutive terms
∴ The sequence is a geometric sequence
∴ The common ratio is 0.5
Answer:
2(47m^3-16n^3)
Step-by-step explanation:
Im assuming the entire room would be 9by9ft for the square walls and 20by9ft for the rectangle walls so you would do 9×9+20×9 which is 81+280= 216ft so she doesnt have enough paint
