Yani buys a certain brand of cereal that costs $10 per box. Yani changes to a super-saving brand of the same size. The equation

shows the price, y, as a function of the number of boxes, x, for the new brand. y = 7x Part A: How many more dollars is the price of a box of Yani’s original brand of cereal than the price of a box of the super-saving cereal? Show your work. Part B: How much money does Yani save each month with the change in cereal brand if he buys 5 cereal boxes each month? Show your work.

A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one. Proof:
Suppose 1 box is bought of each (x=1),original will cos10 & the cheaper $7
b) Each time he buys a cheap brand he save $3 ($10-$7), on 5 cheap boxes, he would save $3 x 5 boxes = $15

Plz help me solve this
Nady [450]

Answer:

c = 9.43 cm

Step-by-step explanation:

Here, we want to get the measure of the missing side

By the use of Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

we have this as follows;

The side c represents the hypotenuse as it faces the hypotenuse

We have this as;

c^2 = 5^2 + 8^2

c^2 = 25 + 64

c^2 = 89

c = √89

c = 9.43 cm

What is the value of x?
Andrei [34K]

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

x=2

by the definition of suplementary angles Angle 1+angle 2=______and angle 2+angle 3=_______ than angle 1+ angle 2+ angle 3 by the
SVETLANKA909090 [29]

Answer:

By the definition of supplementary angles, angle 1 + angle 2 = 180° and angle 2 + angle 3 = 180°. Then angle 1 + angle 2 = angle 2 + angle 3 = 180°. Subtract angle 2 from each side. You get angle 1 = angle 3,  or angle 1 ≅ angle 3.

Step-by-step explanation:

<u>The Complete/Correct Question Reads:</u>

By the definition of supplementary angles, angle 1 + angle 2 = _____ and angle 2 + angle 3 = ____ . Then angle 1 + angle 2 = angle 2 + angle 3 ______. Subtract angle 2 from each side. You get angle 1 = ______, or angle 1 ≅ ______.

-------------------------------------------------------------------------------------------------------------

By definition we know that if the Sum of Two Angles is Equal to 180° then the angles are Supplementary.

Now looking at the schematic we can see that <u>our Supplementary angle pairs</u> are:

  • m∠1  and m∠2
  • m∠3 and m∠2  

So let us start solving.

m∠1  + m∠2 = 180^{o}

m∠3 + m∠2 =180^{o}

Then, we have

m∠1  + m∠2 =  m∠3 + m∠2 =180^{o}

<u>So subtracting </u>m<u>∠2 from each side we have</u>:

m∠1  + m∠2 - m∠2 =  m∠3 + m∠2 - m∠2

m∠1 = m∠3  OR  m∠1 ≅ m∠3  

<u>So your paragraph will be:</u>

By the definition of supplementary angles, angle 1 + angle 2 = 180° and angle 2 + angle 3 = 180°. Then angle 1 + angle 2 = angle 2 + angle 3 = 180°. Subtract angle 2 from each side. You get angle 1 = angle 3,  or angle 1 ≅ angle 3.
