You can think that for every 5 glue sticks, you will have 2 glue bottles. Since 35 means 5×7, then the number of glue sticks will be 2×7 which is 14
Answer:
The value of the determinant is 0.
Step-by-step explanation:
Since it is a 3 x 3 determinant, we can calculate its value by the Law of Sarrus:



The value of the determinant is 0.
Answer:
i=0
Step-by-step explanation:
8(1+2i)-(7-3i)=1+5i
8+16i-7+3i=1+5i
1+19i=1+5i
1+19i-5i=1
1+14i=1
14i=1-1
14i=0
i=0/14
i=0
Hello from MrBillDoesMath!
Answer:
a = 2.7
Discussion:
(2/3) ( 6a + 9 ) = 16.8 => the Distributive law
(2/3) (6a) + (2/3)9 = 16.8 =>
4a + 6 = 16.8 => subtract 6 from both sides
4a = 16.8 -6 = 10.8 (divide both sides by 4)
a = 10.8/4
= 2.7
Thank you,
MrB
