Answer:
Justin-x/3+2 Justin-23 Aimee-42
Step-by-step explanation:
M-x=63
T-x/3+2=63/3+2=23
A-2(x/3+2)-4=2(63/3+2)-4=42
Answer: the answer is 2.5
I just did that
Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm
Note that:
1km = 1,000,000mm
1m = 1000mm
1cm = 10mm
Therefore,
5 km = 5 × 1,000,000mm = 5,000,000mm
7000,000 cm = 7,000,000 × 10 = 70,000,000mm
6,000 m = 6000 × 1000 = 6,000,000mm
Therefore, from the least to the greatest will be:
5km, 6000m, 8,000,000 mm, 7000000 cm
5x + y = 8
Given the equations:
x+3y=10 ____ (1)
2x−y=−1 ____ (2)
Multiply (2) by 2
2(2x - y = - 1) = 4x - 2y = - 2
4x - 2y = - 2 - - - (3)
Add (1) and (3)
4x - 2y = - 2
x + 3y = 10

_________
x = 2, y = 9 or (2,9)
Hello!
The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1
We can plug in the first equation into the second like this:
2x + y = 13 (we know y so we can plug it in)
2x + (5x - 1) = 13
2x + 5x - 1 = 13
7x - 1 = 13
Now we add 1 to both sides
7x - 1 + 1 = 13 + 1
7x = 14
x = 2
Now we plug in x to find y:
y = 5x - 1
y = 5(2) - 1
y = 10 - 1
y = 9
