Answer:
Step-by-step explanation:
x - y = (6 - 5)(y - x) → False
(x - y) (6 - 5) = 1 → False
x- y = (1)(x - y) → True
x - y = 1 + (x - y) → No solution, False
x - y = (6 - 5)(x - y) → True
Answer:
4.4x+9.4
Step-by-step explanation:
x(3.8)-x(2.6)+3+3.2(x)+3.2(2)
3.8x-2.6x+3+3.2x+6.4
Combine all of x's with the blanks
4.4x+9.4
Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
7 1/4 + 5 3/5
First, you need a common denominator to add the two. 20 will work.
4x5=20, so we have to also multiply 1 by 5.
4x5=20, 1x5=5
5x4=20, so we have to also multiply 3 by 4.
5x4=20, 3x4=12
And now we put the fractions back in.
7 5/20 + 5 12/20
And add them.
7 5/20 + 5 12/20 = 12 17/20
Now, we're supposed to reduce it to its lowest form.
Unfortunately, the fraction cannot be reduced, because 17 is a prime number, meaning there are no factors to it except one and itself.
Therefore, the lowest form of 12 17/20 is 12 17/20
Your answer is B, 12 17/20
