Answer:
The value of x is -6
Step-by-step explanation:
Let us equate the fraction by its equivalent
∵ = -22
→ Multiply both sides by (x - 10) to cancel the denominator of the left side
∴ × (x - 10) = -22 × (x - 10)
∴ 352 = -22(x - 10)
→ Simplify the right side by multiplying -22 by the bracket (x - 10)
∵ 352 = -22(x) - 22(-10)
∴ 352 = -22x + 220
→ Add 22x to both sides
∵ 22x + 352 = -22x + 22x + 220
∴ 22x + 352 = 220
→ Subtract 352 from both sides
∴ 22x + 352 - 352 = 220 - 352
∴ 22x = - 132
→ Divide both sides by 22 to find x
∴
∴ x = -6
∴ The value of x is -6
City A is 25% less than population of city B. So city A's population is 75% of city B
<h3><u>Solution:</u></h3>Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,
A = 0.75B can be written as,
city A = 75 % of City B
Thus city A's population is 75% of city B
