Maybe a picture of what the assigment is can help me give you an answer?
Jon=x-2 jor=x
2(x-2)=x+6
2x-4=x+6
combine like terms
x=10 Jordan's age
x-2 or 10-2 =8 Jonathan's age
13-10= 3 years apart
when aylon was 3 Karina was 6
2×3 =6
this was 7 years ago(answer)
10-3=7
13-6=7
48-36=12 years apart
when kd was 6 and md 18
3×6=18
30 years ago
36-6=30
48-18=30
Answer:
2 real solutions
Step-by-step explanation:
Get all the terms to one side
10n^2 = 10 - 8n
10n^2 +8n -10 =0
ax^2 +bx+c =0
The discriminant is
b^2 -4ac
8^2 - 4(10)(-10)
64 +400
464
If the discriminant is greater than 0 we have 2 real solutions
Answer:
4x-2
Step-by-step explanation:
6-3/4x+1/3=1/2x+5
6+1/3-5=1/2x+3/4x
4/3=5/4x
x=16/15
