Answer:
286
Step-by-step explanation:
If the three-digit number is xyz, then:
x + y + z = 16
y = z + 2
z = 3x
Substitute the third equation into the second:
y = 3x + 2
Substitute this and the third equation into the first:
x + (3x + 2) + (3x) = 16
7x + 2 = 16
7x = 14
x = 2
y = 3x + 2 = 8
z = 3x = 6
The number is 286.

Answer:
€16.40
Step-by-step explanation:
First, we need to divide £12.30 by 3 to find out how many groups of 3 there is:
12.3 ÷ 3 = 4.1
Now we can multiply this by 4 to find the euro equivalent:
4.1 * 4 = 16.4
So £12.30 is €16.40

Answer:
The x intercept is (8,0)
Step-by-step explanation:
To find the x intercept set y = 0 and solve for x
Y=3/4x - 6
0 =3/4x - 6
6 = 3/4x
4/3 *6 = 4/3*3/4x
8 =x
The x intercept is (8,0)
