Answer:
10 over 16
Step-by-step explanation:
If you multiply 5 by a number then you have to multiply 8 by the number to keep it equivalent
The pic is kinda blurry so I can’t read it
area of rectangle = l×b
So, area of drawing = l×b = 8cm×4cm = 32cm²
yes.
this is division. 36 divided by 12 is 3. 63 divided by 21 is 3.
Answer:
(x, y) = (-4, 15)
Step-by-step explanation:
The two equations have the same coefficient for y, so you can eliminate y by subtracting one equation from the other. Here the x coefficient is largest for the first equation, so it will work best to subtract the second equation.
(3x +y) -(2x +y) = (3) -(7)
x = -4 . . . . . . . . simplify
Now, we can find y by substituting this value for x.
2(-4) +y = 7
y = 7 +8 = 15 . . . . . add 8 to both sides of the equation
The solution is (x, y) = (-4, 15).
