Let x be the unknown number.
<span>7x + 668 </span><<span> 2000</span> => 7x plus 668 is less than 2000
where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.
7x + 668 < 2000
- 668 -668
7x < 1332
÷7 ÷7
x < 190.30
or
x < 190
To check:
7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000
Answer:
The answer is(D.) 9 cm and 10 cm
5x - 7 < 2x - 1
Take away 2x from both sides:
3x - 7 < -1
Add 7 to both sides:
3x < 6
Divide by 3 on both sides :
x < 2
------------------------------------------------------------
Answer: x < 2

Answer:
Slope of line B: 1/3
Step-by-step explanation:
To find a slope perpendicular to another slope, you take its negative reciprocal.
Therefore, line B will have a slope of 1/3 because -3 -> -1/3 -> 1/3
Length of arc, s = rθ, θ is in radians.
s = rθ
6π = 9θ
9θ = 6π
θ = 6π/9 = 2π/3 radians
