Answer:

Total crackers on the plate are 12

Step-by-step explanation:

Manuel ate crackers = \frac{1}{3}

His brother ate crackers = \frac{1}{4}

Crackers left on the plate = 5

We need to find how many crackers were there on the plate.

Let x be the total crackers on the plate

So, we can write the equation

x-\frac{1}{3}x-\frac{1}{4}x=5

Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5

\frac{12x-4x-3x}{12}=5\\\frac{12x-7x}{12}=5\\\frac{5x}{12}=5\\x=\frac{5*12}{5}\\x=12

So, we get x = 12

Therefore, total crackers on the plate are 12

Determine the number of solutions for each equation
Kay [80]
8. There is no solution. The absolute value of a number is always positive.
9. There are two solutions. Since the absolute value of a number is always positive, a solution can either be 4 or -4.
10. There is no solution because of the same reason for number 8.
11. There is one solution. There really is not -0.
12.  There are two solutions. Since the absolute value is always positive, the solution can be either 15 or -15.

AD= in<br> Help me please, stuck on this question. Thankss
Hatshy [7]

Using the cosine ratio, the value of AD in the diagram is: 2√3π in.

<h3>How to Apply the Cosine Ratio?</h3>

If we have the following given in a right triangle like triangle ADC in the diagram:

AC = 4π (hypotenuse)

AD = ? (adjacent side)

The cosine ratio, CAH would be applied, which is:

Cos 30 = adjacent/hypotenuse

Cos 30 = AD/4π

AD = cos 30 × 4π = √3/2 × 4π [cos 30 = √3/2]

AD = 2√3π in.
