2x + y = x - y - 3 = 6
Add 3 to everything
2x + y + 3 = x - y - 3 + 3 = 6 + 3
2x + y + 3 = x - y = 9
2x + y + 3 = 9
2x + y = 6 = x - y
Add y to everything
2x + 2y = 6 + y = x
Since x = 6 + y substitute every x with 6 + y
2(6 + y) + 2y = x
12 + 4y = x
This is as simplified as I can get and then just place 12 + 4y into every x in the original problem then solve
Answer:
Answer c: 
Step-by-step explanation:
Hi there!
Let´s start writting the formula
If we multiplicate both sides by (x₂ - x₁):
Then if we add y₁ to both sides of the equation:
Then, the right answer is the answer c)
Have a nice day!
Answer:
no
Step-by-step explanation:
A trapezoid is shown, not a bag. If we assume that this shape is supposed to be the front of the bag, Mariam does NOT have enough pink fabric to make the front of the bag from pink fabric.
The area of the trapezoid shown is ...
A = (1/2)(b1 +b2)h
A = (1/2)(9 in + 8 in)(15 in) = 127.5 in^2
This area is larger than the amount of fabric Mariam has, so she does not have enough.
Answer:
Milk: 1000 ml
Flour: 480 g
Butter: 250 g
Step-by-step explanation:
To calculate the amount of butter you have to figure out more flour she used.
First, 480 ÷ 120 = 4 So she uses 4 times the amount of flour.
Then, 60 × 4 = 240
Next, you need the amount of milk so we also multiply by 4.
250 × 4 = 1000
Lastly, have a great day!
