Answer: u = -6

Step-by-step explanation:

first, we move the terms.

5u - 9u = 30 - 6

then, i collected the like terms and calculated them.

-4u = 24

then, i simply divided both sides.

u = -6

Arnold wants to buy two bicycles. Which shop provides the lowest price on the bicycles?

In-s [12.5K]

Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00

Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00

Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)

Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00

B) Walt's Wheels provides the lowest price for two bicycles.

]solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumf

Anna35 [415]

Answer:

$\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument

Step-by-step explanation:

Circumference of circle = $\pi \cdot d$

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to $\frac{360^{\circ}}{n^{\circ}}$

So, Number of sectors = $\frac{360^{\circ}}{n^{\circ}}$

The arc length of each sector is the circumference divided by the number of sectors

$\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}$

Diameter d = 2r (r = radius)

$\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$

Option b is true

Hence $\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}$ best completes this argument

It costs a lumberyard $2.05 per cubic foot of lumber. If they sell the lumber back to their customers for $21.98 per cubic foot

adelina 88 [10]

Answer:

The profit per year will be $23916

Step-by-step explanation:

Cost price of 1 ft³ = $2.05

Selling price of 1 ft³ = $21.98

Profit = Selling price - cost price

profit = $21.98 - $2.05

Profit = $19.93

Profit on 1 ft³ is $19.93

If they sell 100 monthly, per year (12 months), profit will be

19.93*100*12

= $23916
