3x + 12
The GCF here is 3.
3x / 3 = x
12 / 3 = 4
So we have 3(x + 4)
7y - 7
The GCF here is 7.
7y / 7 = y
-7 / 7 = -1
So we have 7(y - 1)
5x + 30y
The GCF here is 5.
5x / 5 = x
30y / 5 = 6y
So we have 5(x + 6y)
8m + 36n
The GCF here is 4.
8m / 4 = 2m
36n / 4 = 9n
So we have 4(2m + 9n)
Let 1st integer = xLet 2nd integer = x + 1 We set up an equation. x(x + 1) = 195 x2 + x = 195 x2 + x - 195 = 0
We will use the quadratic formula: x = (-b ± √(b2 - 4ac) / (2a) x = (-1 ± √(1 - 4(-195))) / 2 x = (-1 ± √(781)) / 2 x = (-1 ± 27.95) / 2 x = 13.48x = -14.78
<span>We determine which value of x when substituted gives us a product of 195.</span> 13.48(14.48) = 195.19-14.48(-13.48) = 195.19 <span>The solution is 2 sets of two consecutive number</span> <span>Set 1</span> The 1st consecutive integer is 13.48The 2nd consecutive integer is 14.48
<span>Set 2</span> The 1st consecutive integer is -14.48The 2nd consecutive integer is -13.48Hopefully this helped, hard work lol :)
Okay, so here are the answers..
1. 3 • (5 • x)
2. 5 • (x • 3)
3. 15x
You're welcome, and I took the test. :T
Answer:
right angle i think
Step-by-step explanation:
Answer:
The rest of the question is the attached figure
The percent change =
If (+ve) increase and if (-ve) decrease
Part A: What is the percent of change in the cost of a pizza?
The initial price = $7.5
The final price = $9
The percent change = %
Part B: What is the percent of change in the cost of a cheeseburger?
The initial price = $5
The final price = $6.5
The percent change = %
Part C: What is the percent of change in the cost of a serving fries?
The initial price = $2
The final price = $4.5
The percent change = %
Part D: What is the percent of change in the cost of a hot dog?
The initial price = $2.5
The final price = $2
The percent change = %
i found this online i hope if helps you
