Answer: explanation
Step-by-step explanation:
1. answer:2592
explanation: it says to find the % of the small sample so 45 out of 75 is 60% then says to convert it into a decimal and multiply it by 4,320 which equals 2592.
2. answer:
explanation:540 is 12% of 4500. I don't quite understand what that number is but I'm assuming it's the percentage number and that number is 12 and that's 12% out of 100. if it means what percentage 540 is out of 100 then its 540%
3. answer:30
explanation: 4 out of 20 is 20% converted to decimal is 0.2 then multiply it by 15 0 and that adds to 30.
i hope this helped and i hope its correct
Answer:
Solve the 1st equation for y and then you substitute the answer of the y value to the other equation to get the x value
Answer:
x = -15
Step-by-step explanation:
3x-5=2(2x+5)
Expand by using distributive property
3x - 5 = 4x + 10
Subtract 4x from both sides
3x - 5 - 4x = 4x + 10 - 4x
Simplifying
-x - 5 = 10
Add 5 to both sides
-x - 5 + 5 = 10 + 5
Simplifying
-x = 15
Divide both sides by -1
x = -15
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ￮ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
The sum of the angles equals 180
therefore
x+(1/4x)=180
1 1/4 x = 180
x=180/ 1 1/4
x=144
1/4 x =1/4(144)=36
