643 will round to 600 and 189 will round to 299 so 600 - 200 = 400

A sports store received a shipment of 400 baseball gloves, 30% were left-
noname [10]
280 right handed gloves. First, we'd need to find out the amount of left handed gloves. We do this by multiplying 0.3 (which is basically 30%) by the total number of gloves. This is because we are finding out 30% of the 400 gloves, and "of" represents multiplication. We get 120. Then, we subtract that number from 400 to get the amount of right handed gloves, which is 280. hope this helps :)

-1/4b + 1/2 = 5/6<br>Find b​
QveST [7]

Answer:

b = -4/3

Step-by-step explanation:

First, subtract the 1/2 over

-1/4b+1/2=5/6

5/6-1/2

To get a common denominator of 6, multipy 1/2 by 3

5/6-1/2(3)

5/6-3/6=2/6

-1/4b=2/6

Next, multiply by the reciprocal of -1/4, or -4

(-4)-1/4b=2/6(-4)

b=-4/3

This is actually called a mapping diagram but the answer is C.

Because the right circle represents the x variable and the left circle is the y variable. So you just follow the arrows. -3 is pointing to 4 so that's a pair or (-3,4)
