Answer:
You'll need 18 cups of chicken broth!
Step-by-step explanation:
You are using a ratio of 1/4 cup (lentils) to 2 cup (broth). Therefore, you need to find the relationship between lentil and broth.
- In order to get from 1/4 to 2, you multiply by 8. (1/4 * 8 = 2)
- Therefore, the common relationship is multiplying the lentil amount by 8
- So, 2 1/4 * 8 = 18
Therefore, 18 cups are needed :D
The rule for secants tells you
EC·ED = EB·EA
(x+4)(x+5) = (x+1)(x+12)
9x+20 = 13x+12 . . . . . . simplify, subtract x²
8 = 4x . . . . . . . . . . . . . . add -12-9x
2 = x
The value of x is 2.
4/7 because the equation would be 2(7-5)
over
5+2
so it would be
2(2)
over
7
and then it would be
