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:
c = -10
Step-by-step explanation:
Divide both sides by -3
simplify
c - 1 = -11
add 1 to both sides
c - 1 + 1 = -11 + 1
simplify
c = -10
Answer:
x=2 x=-2
Step-by-step explanation:
x² + 2x - 4 = 2x
Subtract 2x from each side
x² + 2x-2x - 4 = 2x-2x
x^2 -4 = 0
Factor
We know this is the difference of squares
(x-2)(x+2) =0
Using the zero product property
x-2 =0 x+2 =0
x=2 x=-2

Since it’s not x3 it must be +8 so if i were you i’d pick B
