Answer:
t=2
j=1
Step-by-step explanation:
3 tacos and a juice is $7
3t+j=7
4 tacos and 2 juices is $10
4t+2j=10
We have a simultaneous equation. It can be solved either by substitution method or Elimination method. For the purpose of this question, the elimination method will be used
3t+j=7 Equation 1
4t+2j=10 Equation 2
To eliminate j, we multiply Equation 1 by 2, the coefficient of j in equation 2, so that in both equations, j can have the same coefficient.
2(3t+j=7)
6t+2j=14 Equation 3
We now have
4t+2j=10 Equation 2
6t+2j=14 Equation 3
We subtract equation 2 from equation 3, to eliminate j
6t-4t=2t
2j-2j=0
14-10=4
We have 2t=4
Divide both sides by 2
2t/2=4/2
t=4/2
t=2
Substitute t for 2 in equation 1, to get j
3t+j=7
3(2)+j=7
6+j=7
j=7-6
j=1
One taco cost $2 while 1 juice cost $2
Let's assume that the total daily allowance of fat is given, otherwise let's just assign a variable for it.
We can make the formula based on the given data.
Percentage = Total daily allowance of fat given / total intake of fat per day * 100
So, the equation Percentage = Total / 48 * 100 will be used in order to get the percentage of the total amount.

Answer:
1 ft³
Step-by-step explanation:
The formula for the volume of a cube is
Vol. = l³ = l × l × l
If l = 1 ft,
V = 1 ft × 1 ft × 1 ft
V = 1 ft³
