Solve for x.
7x = 78

Answers

1.142 is the value of x in the equation 7x = 78.

The given equation is 7x = 78

In the equation x is the variable.

We need to find the value of x.

Divide both sides by 7 to get the value of x

x=78/7

x=11.142

Hence, the value of x in the equation 7x = 78 is 11.142.

The lengths of the sides of a quadrilateral are consecutive even integers. twice the length of the shortest side plus the length of the longest side is 248 inches. find the length of the longest side.

Answers

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above: twice the length of the shortest side plus the length of the longest side is 248 inches.

2. Therefore, keeping on mind the information above, you have:

x: the shortest side
x+6: the longest side

2x+(x+6)=248
3x+6=248
3x=242
x=242/3
x=80.66 (The shortest side)

x+6=80.66+6=86.66 (The longest side)

The answer is: 86.66

Final answer:

The length of the longest side is 86 inches.

Explanation:

To solve this problem, let's represent the lengths of the consecutive even integers as x, x+2, x+4, and x+6. According to the given information, we can write the equation 2x + (x+6) = 248. Simplifying this equation, we get 3x + 6 = 248. Subtracting 6 from both sides, we have 3x = 242. Finally, dividing both sides by 3, we find x = 80. Therefore, the length of the longest side is x + 6 = 80 + 6 = 86 inches.

Find the width of a rectangle with a perimeter of 90 and a length of 15.A.90
B.15
C.45
D.30
I really need help.

Answers

A rectangle has 2 sets of equal parallel lines. And we know one of the sides is 15.
So we know two of the sides have to be 15. Right?

So that means 15 x 2 = 30

So we know that two of the sides add up to equal 30.

The entire perimeter is 90. Well we've used 30 so lets see how much we have left to use.

90(the entire perimeter) - 30(the amount we know) = 60(what we have left)

So the last two sides of the rectangle equal 60, since there are two sides, let's divide the remaining perimeter by 2

60(both of the sides) / 2(the last 2 sides that we haven't found the length for yet) = 30

So now we know all of the sides.

Let's read the question again now.

"Find the 'WIDTH' of a rectangle with a perimeter of 90 and a 'LENGTH' of 15"

So it's 15 long(length), and 30 wide(width)

If this doesn't help, I can draw a picture and it mights make some more sense :)

Final answer:

The width of the rectangle is 30 units.

Explanation:

To find the width of a rectangle, we need to use the formula for the perimeter of a rectangle, which is 2(length + width). In this case, we are given the perimeter as 90 and the length as 15. Plugging these values into the formula, we get: 90 = 2(15 + width).

Now we can solve for the width. First, simplify the equation: 90 = 30 + 2(width).

Then, subtract 30 from both sides: 60 = 2(width). Divide both sides by 2 to isolate the width: width = 30.

Therefore, the width of the rectangle is 30 units.
