Answer:
5/9
Step-by-step explanation:
Let's define:
The following three equations are established from the question:
sw + j + sk = 120
sw/j = 8/3
j/sk = 3/4 or sk/j = 4/3
Dividing the first equation by j, we get:
sw/j + j/j + sk/j = 120/j
8/3 + 1 + 4/3 = 120/j
5 = 120/j
j = 120/5 = 24
sw = 24*8/3 = 64
sk = 24*4/3 = 32
After the replacement the new number of jeans and skirts are:
j' = 24 - 4 = 20
sk' = 32 + 4 = 36
the new ratio of jeans to skirts is:
j'/sk' = 20/36 = 5/9
Answer:
66 inches
Step-by-step explanation:
This implies that in this specific town in Texas, an average of 30 inches of rain falls every two weeks.
Amount of rain received every two weeks (14 days) = 30 inches.
For a 31 day month, we have:
= 2
Therefore for a 31 day month, the amount of rain received by the town can be determined as;
= 30 x 2
= 66.4285
= 66 inches
The amount of rain received by the town is 66 inches for the 31 days.
Answer:
Baseball gloves = 17 gloves || Bats = 11 bats
Step-by-step explanation:
Let baseball gloves be x and bat be y
<em>Possible Equations:</em>
x + y = 28
29x + 14y = 647
-----------------------------------
make x the subject:
x + y = 28
x = 28 - y .........equation 1
29x + 14y = 647
x = (647 - 14y)/29 .........equation 2
----------------------------------------------------------------
<u>Solve them simultaneously:</u>
28 - y = (647 - 14y)/29
29(28 - y) = 647 - 14y
812 - 29y = 647 - 14y
-14y + 29y = 812 - 647
15y = 165
y = 11
So the number of bats he sold is 11 bats.
number of gloves he sold: x = 28 - y
: x = 28 - 11
: x = 17
So number of baseball gloves he sold is 17 baseball gloves.
