66inches long is to be cut into 5 1/2 inches pieces how many pieces can be cut

1 answer:

7 0

Each piece will be the same length. We can convert 5 1/2 into an improper fraction. 5 1/2 = 11 / 2 Divide 66 by this improper fraction. 66 / (11 / 2) When we divide by a fraction, we multiply by the reciprocal of that fraction. 66 * (2 / 11) = 2 * 6 = 12 12 pieces can be cut.

A triangle is such that the largest angle is 7 times the smallest angle. The third angle is 15 less than the largest angle. Find

Tcecarenko [31]

Answer:

The smallest angle measures 13°, the largest angle measures 91° and the third angle measures 76°

Step-by-step explanation:

Let's recall that the interior angles of a triangle add up to 180°, therefore we have:

Smallest angle = x

Largest angle = 7x

Third angle = 7x - 15

Now, we can solve for x, using the following equation:

x + 7x + 7x - 15 = 180

15x = 180 + 15

15x = 195

x = 195/15

x = 13 ⇒ 7x = 91 ⇒ 7x - 15 = 76

The smallest angle measures 13°, the largest angle measures 91° and the third angle measures 76°

Solve the following system of equations: 4x+5y=23 -3x-7y=-14

Korvikt [17]

Basically you're solving for both variables here.
I prefer elimination method so that is what I used.
I started off by multiplying each equation in order to get one of the variables at the same value so it would be possible to cancel it out.
Multiplying the first equation by 3 gave me,
12x + 15y = 69
Then I multiplied the second equation by 4,
-12x + 28y = -56
As you can see, it's not possible to cancel out the x variable.
12x + 15y = 69
+(-12x + 28y = -56)
_____________
13y = 13
Then just solve for y which gives you -1.
After you have one variable solved simply insert it into one of the original equations to find the other variable.
4x + 5(-1) = 23
4x - 5 = 23
4x = 28
x = 7.
And there you have it! Hope this helped!
