Answer:

12 = 1/2(x)(5x - 2)

Bonus solution for x = 2.4 ft

Step-by-step explanation:

area = 1/2xh

h = 5x - 2

12 = 1/2(x)(5x - 2)

24 = 5x² - 2x

5x² - 2x - 24 = 0

x² - 0.4x - 4.8 = 0

(x - 2.4)(x + 2) = 0

x = 2.4

A number, n, is multiplied by - 5/8. The products is - 0.40 What is the value of n? It would also help if you would explain how
Kay [80]
I'm not sure if those numbers are negatives or thats just a hyphen but:

N(-5/8)=-0.40

Division is always the opposite of multiplication

-0.40/(-5/8)=0.64

N=0.64

A baker makes apple tarts and apple pies each day. Each tart, t, requires 1 apple, and each pie, p, requires 8 apples. The baker
Lynna [10]
For this case, the first thing we must do is define variables.
 We have then:
 t: number of tarts
 p: number of pies
 We now write the system of equations:
 Each tart, t, requires 1 apple, and each pie, p, requires 8 apples. The baker receives a shipment of 184 apples every day:
 8p + t ≤ 184
 the baker makes no more than 40 tarts per day:
 t ≤ 40
 Answer:
 A system of inequalities that can be used to find the possible number of pies and tarts the baker can make is:
 D. t ≤ 40
 8p + t ≤ 184
