Answer:
Step-by-step explanation:12y ×4 =21
48y=21
Y=0.44
Mark brainlest if correct pls
Answer:
I would change 2x+4y=24 into x=12–2y
To do that, divide both sides by 2 and then subtract 2y on each side.
After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.
Then solve.
3(12–2y)+2y=19
36–6y+2y=19
-4y+36=19
-4y=-17
y=4.25
Then, substitute y in either equation.
Either this:
3x+2y=19
3x+2(4.25)=19
3x+8.5=19
3x=10.5
x=3.5
Or:
2x+4y=24
2x+4(4.25)=24
2x+17=24
2x=7
x=3.5
Or you could solve it in the equation you created in the beginning:
x=12–2y
x=12–2(4.25)
x=12–8.5
x=3.5
The coordinates where the lines intercept are (3.5, 4.25).
Sorry for the long answer!
In real life, there are 35 days until the 4th of July.
In the problem, if Brooke is correct, there are 49 days until the 4th of July.
This question is weird.
Answer:
3z-44
Step-by-step explanation:
All you have to do is to simplify the numbers. 2 + 6 - 52 = -44.
I assumed you meant red instead of wet.
To calculate this, multiply 28% (which is the same as .28) times 300.
300 x .28 = 84
