Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10
Answer:
m = -4/3 b = 0
Step-by-step explanation:
Slope formula is
The slope is -4/3. The line intersects the y-axis at (0 , 0) so b = 0. This can be verified by plugging one of the points into the equation.
The value of 4 in 34,256 is 4,000. The value of 4 in 47,163 is 40,000.
