14 is the answer for this one
Answer: each soda costs $1.5 and each hotdog costs $3.
Step-by-step explanation:
If H is the price for one hotdog and S is the price for one soda, we have the equations:
for Jack.
3*H + 2*S = $12
For Angie.
1*H + 4*S = $9
Now we can isolate one of the variables in one of the equations and then replace it in the other equation, let's isolate H in the second equation:
H = $9 - 4*S
now we replace it in the first eq
3*H + 2*S = $12
3*($9 - 4*S) + 2*S = $12
$27 - 12*S + 2*S = $12
-10*S = $12 - $27 = -$15
S = $15/10 = $1.5
Now we can replace it in the equation for H and get:
H = $9 - 4*$1.5 = $3
So each soda costs $1.5 and each hotdog costs $3.
Step-by-step explanation:
y-intercept (0,2.5)
x-intercept (3.5,0)
Since neither 5x nor -y has a "like term" in <span>2xy+xy, the sum of these quantities is simply
</span><span>2xy+xy + 5x - y = 3xy + 5x - y
You might want to write this as y(3x -1) + 5x. </span>
Answer:
12
Step-by-step explanation:
The area of a parallelogram is equal to its base times its height. Segment DX is a height relative to the base BC, so (area of ABCD) = BC times DX,
144 = 12 times DX.
So, DX is 12. :)
