Answer:

B

Step-by-step explanation:

For each box, there is 1 defective lightbulb. Therefore, a delivery of 4 boxes will have 4 defective lightbulbs. A delivery of 2 boxes has 2 defective lightbulbs. 4 defective lightbulbs subtracted by 2 defective lightbulbs equals 2 more defective lightbulbs in 4 boxes than 2. Therefore, it is B.

The speed of a river current is 7 mph. If a boat travels 20 miles downstream in the same time that it takes to travel 10 miles u
dem82 [27]

Answer:

  21 mph

Step-by-step explanation:

The relationship between time, speed, and distance is ...

  time = distance/speed

The speed downstream is b+7 if the boat's speed is b. The speed upstream is b-7, and the times in each direction are equal. This means ...

  20/(b+7) = 10/(b-7) . . . . . . time in each direction are the same

  20(b-7) = 10(b+7) . . . . . . . cross multiply

  (20-10)b = 7(10+20) . . . . . add 7(20)-10b

  b = 7(20 +10)/(20 -10) = 21 . . . . mph

The speed of the boat in still water is 21 mph.

For number 1, add the sides of the triangle. They are all given. The answer is 19.

For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.

For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.

For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.

For number 5, add all the sides together like number 1. The answer is 18.

Answer:

B. y + 7 = -6/5 (x+3)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = − 6 /5 x − 53 /5

Point-slope form:  y + 7 = − 6 /5 ⋅ ( x + 3 )
