Answer:
$12.00 all together.
Step-by-step explanation:
there is only 2 people him and his sister.
They both purchase 2 ticket for $1.25
so 4 tickets all together
1.25x4=$5
They they both get one soda for $3.50
$3.50+$3.50=$7
$7+$5=12
So they spent $12
For this question, you would want to set up a system of equations.
Let x = Dog Food
Let y = Cat Food
5x+2y=20
x+4y=13
The next step is to eliminate a variable or do substitution. I personally find elimination easier. To eliminate the y, multiply the top equation by -2.
-10x-4y=-40
x+4y=13
The y's will cancel and you are left with:
-9x=-27
Divide by -9 on both sides and you get x=3. Now you want to take 3 and substitute it back into one of the original equations.
3+4y=13
Solve for y
4y=10
y=2.5
Plug both values into the top equation to check the values.
5(3)+2(2.5)=20
15+5=20
20=20
The answers are correct. Dog food is 3 dollars or euros and cat food is 2.50 euros.
Please mark brainiest and good luck :D
For this question you want to take 83 and subtract 56 which would give you 27. So 33 couldn't be the number of cows still in the barn.
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
The x-axis brainliest plz :)
