Answer:

a4 = 128

a5 = -512

Step-by-step explanation:

a1= -2

q= (-1)^(n+1) × 4

a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128

a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512

Zer - 25$ Soil- 6.25 Jamie is starting a garden. She buys 3 bags of potting soil and 4 bags of fertilizer. In all she spent 125$
erastovalidia [21]

Answer:

The price of fertilizer is $27.5  and potting soil is $5

Step-by-step explanation:

I think that you are asking for the price of each bag of fertilizer and potting soil. And here is my answer:

Given the system of linear:

3s + 4f = 125  <=> f = 31.25 -3/4s (1)

4s + 2f = 75   <=> f = 37.5 -2s (2)

Take (1) -(2) we have:

f -f = 31.25 -3/4s - (37.5 -2s)

<=> 0 = -6.25 + 1.25s

<=> 1.25s  = 6.25

<=> s = 5

=> f = 37.5 -2(5) = 27.5

So the price of fertilizer is $27.5  and potting soil is $5

Pleaseeeee help meeee……………
hram777 [196]

Answer:

104°

Step-by-step explanation:

In order to find out the value of x we must figure out the other angles. The line on the extended side adds up to 180 degrees. Use that information to find the other angle.

180 - 128 = 52

The one angle is 52. Then, we know that a triangles angles always add up to 180 degrees as well. So create an equation:

180 - 52 - 24 = 104
