Answer:
D. a−b=10 a=3b+4
Step-by-step explanation:
Difference between a and b means to subtract b from a
We have,
a-b=10
a is 4 more than 3 times b
4 more than means to add 4
3 times b means to multiply b by 3
Therefore, a=3 times b + 4
a=3b+4
a - b=10; a=3b+4
I don't believe your expression is correct as is; it should be <span>100(1 + 0.4)^h.

Answer:
The answer to your question is: x = 100
Step-by-step explanation:
It's a polygon of 7 sides
The sum of internal angles in a polygon equals 180(n-2), where n = # of sides
Internal angles = 180(7-2)
= 180(5)
= 900°
(x + 50) + (x + 50) + (x + 50) + x + x + x + (x + 50) = 900
4(x + 50) + 3x = 900
4x + 200 + 3x = 900
7x = 900 - 200
7x = 700
x = 700 / 7
x = 100
7/63=1/9 acres per pound of seeds
3/6=1/2 pound flour per dollar
We shall use yards as the unit here.. 3 feet is 1 yard, so we know that the ratio is now 1 yard to 7 yards. We can't reduce this anymore, so this is the final ratio.
