Answer:
5 weeks
Step-by-step explanation:
Let x represent the number of weeks they have been saving
Create an equation that sets Cameron and Sams' savings equal to each other, then solve for x
4x + 20 = x + 35
3x + 20 = 35
3x = 15
x = 5
So, they will have saved the same amount of money after 5 weeks
The line of reflection that would map ABCD onto itself is the line of the diagonal which is -3x + 3y = 9
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The line of reflection that would map ABCD onto itself is the line of the diagonal. The diagonal passes through A(-3, 0) and C(-1, 2), hence:
y - 0 = [(2 - 0)/(-1-(-3))](x - (-3))
y = x + 3
-x + y = 3
-3x + 3y = 9

Answer:
<em><u>1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club</u></em>
<em><u>2) 420 people with 210 per hour</u></em>
<em><u>3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.</u></em>
<em><u>4) 396 quarts per hour and a daily rate of 792.</u></em>
Step-by-step explanation:
1) $3.10 x 2 = $6.20
2) 70 x 6 = 420
so, 210 per hour
3) $1.05 divided by 3 is $0.35 per apple at the Quick Market
$2.55 divided by 5 is $0.51 per apple at the Stop and Save.
4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.
330 + 33 + 33 = 396 for 12 hours
396 x 2 = 792 for one day.
Answer:
12
Step-by-step explanation:
Direct Variation. I think it's gonna be like this.
SInce Z is not inversely to y , its varies directly to both.
Then it's,
Z=kxy, where k is constant.
subst. Z=6,x=2 and y=6.
6=k×2×6
6=k×12=12k
6=12k=½
the formula connecting them is
Z=½xy
Z=½×3×8
Z= 1×3×8÷2
Z=24÷2
Z=12.
That's my solution.
