Answer:
The correct anser is option
B. 2x + 2 = 18
Step-by-step explanation:
Let the number of hot dogs eaten by the runner up be represented by x
If Dave ate 2 more than twice x, this means that the number eaten by him = 2x + 2
Since the total number of hot dogs eaten by Dave is 18
Therefore, the equation will be
2x + 2 = 18
So the number of hot dogs eaten by the runner-up is determined by solving for x
2x= 18-2
2× = 16
x = 16/2
x = 8
The runner up are 8
While Dave are
2×8 + 2 = 18.

Answer:
A = 2000(1.04)^t
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
P is the principal = $2000
r is the rate = 4% = 0.04
On substituting
A = 2000(1+0.04)^t
A = 2000(1.04)^t
Hence the required expression is A = 2000(1.04)^t
Answer: sorry, i couldn't graph it
but the equation was done.
7x+25y =12
rearrange it into y=mx+c
it becomes:
25y = -7x + 12
y= -0.28x+12
to find y intercept: x=0
so
y= -0.28*0+12
y=12
to find x intercept, y=0
so
0= -0.28x+12
0.28x = 12
x= 12/0.28
x= 42.857142857142857142857142857143
approximately = 43(whole number) or 42.9(one decimal place) or 42.86( 2 decimal places)
