Write one digit on each side of 15 to make a four digit multiple of 15. how many different solutions does this problem have? the possible solutions

There are 6 solutions

Step-by-step explanation:

All multiples of 15 are multiples of 5, then all finish in 0 or 5. Therefore, the four digits possibilities are:  1150 , 1155 , 2150 , 2155 , 3150 , 3155 , 4150 , 4155 , 5150 , 5155 , 6150 , 6155 , 7150 , 7155 , 8150 , 8155 , 9150  and 9155 . Only 1155 ,  3150 , 4155 , 6150 , 7155  and 9150  are multiples of 15.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
