Answer:
D) 27
Step-by-step explanation:
It's a rectangle so the opposite sides are congruent to each other.
<em />
<em>Long Side:</em>
6x + 6 = 42
subtract 6 from both sides:
6x = 36
divide both sides by 6:
x = 6
<em />
<em>Short Side:</em>
5y + 5 = 30
subtract 5 from both sides:
5y = 25
divide both sides by 5:
y = 5
<em />
<em>The Equation:</em>
2x + 3y
substitute in the values:
2(6) + 3(5)
do the multiplication:
12 + 15
add the values together:
27
Answer: Rectangular Prism
==================================
Explanation:
A rectangle is a four sided object that has all four angles at 90 degrees (aka right angles). Imagine that the cards are designed as such they do not have their corners rounded off, but each corner is a 90 degree angle. Stacking 52 congruent rectangles leads to a 3D solid known as a rectangular prism. The base is a rectangle that is congruent to any of the 52 cards. This stack must be aligned and not allowed to have any of the cards offset (ie forming a sort of "leaning tower"). You can think of a "rectangular prism" as a "box" which is probably a more common term for it; however, "rectangular prism" is probably what your teacher will want since it likely involves geometric terms you've learned in your lessons.
The answer is definitely going to be a good day for y’all to do a lot more work
Answer:
4 hours
Step-by-step explanation:
We want to find at what x value, will y be the same for both companies. To do this, we can set the two expressions equal to each other.
25x+250=50x+150
To solve, we have to get all the variables to one side of the equation, and all the numbers to the other
Subtract 25x from both sides
250=25x+150
Subtract 150 from both sides
100=25x
Now, we have all the variables on one side, and the numbers on the other.
To isolate the variable, divide by 25
x=4
So, at 4 hours,the cost will be the same
Hope this helps! :)
Y=(1/2)x cause the constant variation is 1/2
