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
Answer:
Step-by-step explanation:
The line BD divides a right angle into two acute angles <CBD + <DBA
They add to 90.
They are therefore complementary.
The word you are looking for is complementary.

Answer:
7 inches
Step-by-step explanation:
I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l
let P represent the perimeter of the window in inches
let w represent the width of the window in inches
let l represent the length of the widow in inches
(L is l whereas one is 1)
So we know w=5 and P=24
This lets us have the equation 24= 2 x 5 + 2l
24=10 + 2l
14=2l
7=l
