One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?

Answers

Answer first number = 57 second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57

Laura fills a bucket with water at a rate of 6 L/min. At the same time, Sarah empties a bucket holding 30 L of water at a rate of 9 L/min. Let l represent the number of liters of water and let t represent time in minutes. The system models this situation.How many minutes will it take for the buckets to hold equal amounts of water, and how much water will that be?

l = 6t

l = 30 – 9t

It will take ____ minutes for both buckets to hold equal amounts of water. They will each hold ____ liters.

Answers

0+6 L per min
30-9 L per min
so let x represent the time
0+6 times x and
30-9 times x
we want to know what time they will be equal so set them equatl to each other
0+6x=30-9x
6x=30-9x
add 9x to both sides
15x=30
divide both sides by 15
x=2
at 2 mins, they will be equal
find out what that is
subsitute in 0+6x
0+6(2)=0+12=12L

the answers are 2 minutes and 12 liters respectively

Find the GCF of the terms of the polynomial.26x² + 34x^4

A. x²
B. 26x²
C. 2x^4
D. 2x²

Answers

the answer choice is d because the the greatest exponent is 4 but you cant take 4 exponents out of 2 . Both numbers are divisible by $2 x^(2)$ which would make the answer $13+17 x^(2)$

26x²: 13 · 2 · x · x
34x⁴: 17 · 2 · x · x

GCF: 2x²

26x² + 34⁴
2x²(13) + 2x²(17x²)
2x²(13 + 17x²)

The answer is equal to D.
