Answer:
i can say its an accute triangle sorrry
Step-by-step explanation:
Lets define the variables
x - burger
y - hotdogs
Now lets write our equation
2x+5y=12.75
3x+2y=12.25
Now we solve by subsitution or elimination.
2x+5y=12.75
0.4x+y=2.55
y=-0.4x+2.55
3x+2(-0.4x+2.55)=12.25
3x-0.8x+5.1=12.25
2.2x=7.15
x=3.25
Plug in X
3(3.25)+2y=12.25
9.75+2y=12.25
2y=2.5
y=1.25
Your final answer is 3.25, 1.25
Plug it in to check!
Answer:
25
Step-by-step explanation:
The daughter is ten which means the wife is 30 (10*3) and the man is 5 years older than the wife (30+5). The man is 35 and the daughter is ten, so subtract ten years from the man (35-10) which means the man is 25 years old
Answer:
8
Step-by-step explanation:
8a-(2b+3c)
a=3
b=5
c=2
You plug in the numbers:
8(3) - (2(5)+3(2))
multiply inside the parenthesis first
24-(10+6)
24-16 = 8
