Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.
Step-by-step explanation:
81 - 1.2x < 55
81 < 55 + 1.2x (add 1.2x to both sides)
1.2x > 26 (subtract 55 from both sides)
x > 21 2/3.
That would be vertical sketch
Answer:
b. - 3x+2
Step-by-step explanation:
1+8+x+y+z=30
9+x+y+z=30
x+y+z=21
1*8*x*y*z=2520
8xyz=2520
xyz=315
2+19=21 19 can't be made with single digit numbers:
not 2
3+9+9=21 9 can't be used twice:
not 3
4+8+9=21 8 is one of the other numbers and 4 can therefore not be used:
not 4
5+7+9=21 and 5*7*9=21
The other 3 numbers are as follows: 5, 7, 9
Hope this helps :)
