x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5.  5x + 12y = 80  5(4) + 12(5)=80  20+60=80. That is all.  I hope that doesn't sound confusing

Your brother eats 1/6th of your birthday pizza. If the pizza has a diameter of 12 inches, what is the area that he ate
Kipish [7]

Answer:

18.84 in^2

Step-by-step explanation:

Area brother ate = 1/6 x area of pizza

a pizza is the shape of a circle. the area of a pizza is equal to the area of a circle

Area of a circle = πr²

r = 12/2 = 6

he diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x 6^2 = 113.04

1/6 x 113.04 = 18.84

Please help me solve this. Please don’t give me a link, or it will be reported. Please provide step by step explanations. Thanks

Answer:

x = 27/10 or x = 2.7

Step-by-step explanation:

Step 1: Get rid of the denominator.

LCD of 4 & 3: 12

Multiply both sides by 12.

12 ( 2x - 1 / 4 ) + 12 ( x / 3 ) = 12 (2)

Reduce the numbers.

3 ( 2x - 1) + 4x = 24

Step 2: Distribute.

6x - 3 + 4x = 24

Step 3: Collect like terms.

6x + 4x = 24 + 3 ( - 3, the sign change when moved to the other side)

10x = 27

Step 4: Solve for x.

Multiply both sides by 10.

10x / 10 = 27 / 10 (the 10 cancels out)

x = 27 / 10 or x = 2.7

Answer: x = 27 / 10 or x = 2.7

Simplify the expression by using a double-angle formula or a half-angle formula. (a) 2 tan(5°) 1 − tan2(5°)
antoniya [11.8K]

The question is related to trigonometry and we have to use the formula of double angle .

Here we use double angle formula of tangent function which is

tan(2x) = \frac{2tan(x)}{1-tan^2(x)}

Given expression is

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}

Comparing it with double angle formula, we will get x = 5

SO the required expression is equal to

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}  =tan(2*5 )

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}  =tan(10 )

So the answer is tan(10) .
