Answer:
ab
Step-by-step explanation:
ac should always be longer for it would be the hypotnuse
Answer:
x = 2
Step-by-step explanation:
The four sides of a rhombus are equal. Thus, 10x + 6 = 4x + 18.
Solve this equation for x:
6x = 12
So, finally, x = 2
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.
First we find the number of males from the percentage given:
0.56 * 103500 = 57960 males
Subtract the number of males from the total population to get the number of females:
103500 - 57960 = 45540 females
You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.
0.44 * 103500 = 45540
The answer is 45540.
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
