x =15.
Step-by-step explanation:
100 - 6x = 160 - 10x
-6x = 160 - 10x - 100
-6x = 60 - 10x
4x = 60
x = 15
Since there are four suits, with each having a 4 and 5, we have 2+2+2+2=2*4=8
Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
Answer:
A. 1:3
