The first thing we must do in this case is to define variables.
We have then:
x = packets of sweet-pepper seeds
16-x = packets of hot-pepper seeds
We now write the equation to solve the problem:
2.32x + 4.40 (16-x) = 2.58 (16)
2.32x + 70.40-4.40x = 41.28
-2.08x = -29.12
x = (- 29.12) / (- 2.08)
x = 14
Answer:
there are in the assortment:
14 packets of sweet-pepper seeds
16-14 = 2 packets of hot-pepper seeds
Answer:
5 x 5 per face x 18 faces = 450 cm
Step-by-step explanation:
I think the answer is 19 tens since u take away a hundred, which is 10 tens and 10 tens + 9 tens equals 19 tens
(B/2)^2 is the formula you need to complete the square
B is the second term which is -6
So let’s plug it into the formula
(-6/2)^2
(-3)^2= 9
