Answer:

Option c) is correct.

The value of y in the given equation is 26 ie., y=26

Step-by-step explanation:

Given equation is

$2(3y+7+5)=196-16$

Now to the find the value of y in the above equation.

To find y simplify the above equation

$2(3y+7+5)=196-16$

$2(3y+12)=180$

Now apply distributive property

$6y+24=180$

$6y=180-24$

$=\frac{156}{6}$

Therefore y=26

Option c) is correct.

The value of y in the given equation is 26 ie., y=26

A pair of belted pulleys have diameters of 18 in. and 12 in. If the smaller pulley turns at 750 rpm, how fast will the larger pu

zhenek [66]

Don’t know if this has to do with pie but if it doesn’t I will do my best attempt 750/12 is 62.5 witch is 520.8% of the diameter so 5.208 x 18 is 93.7 as its unit rate I KNOw I am doing this wrong but hopefully it helps somehow I’m in middle school and it told me I should answer this so good luck

Solve for X ...........

musickatia [10]

Answer:

x = 46

Step-by-step explanation:

Given 2 secants from an external point to the circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

2(2 + x) = 6(6 + 10)

2(2 + x) = 6 × 16 = 96 ( divide both sides by 2 )

2 + x = 48 ( subtract 2 from both sides )

x = 46

what is the polynomial function of lowest degree with leading coefficient of 1 and roots 2 and 1 + square root2

Marta_Voda [28]

If the roots to such a polynomial are 2 and $1+\sqrt2$ , then we can write it as

$(x-2)(x-(1+\sqrt2))$

courtesy of the fundamental theorem of algebra. Now expanding yields

$(x-2)(x-1-\sqrt2)=x^2-2x-(1+\sqrt2)x+2(1+\sqrt2)=x^2-(3+\sqrt2)x+2+2\sqrt2$

which would be the correct answer, but clearly this option is not listed. Which is silly, because none of the offered solutions are *the* polynomial of lowest degree and leading coefficient 1.

So this makes me think you're expected to increase the multiplicity of one of the given roots, or you're expected to pull another root out of thin air. Judging by the choices, I think it's the latter, and that you're somehow supposed to know to use $1-\sqrt2$ as a root. In this case, that would make our polynomial

$(x-2)(x-(1+\sqrt2))(x-(1-\sqrt2))=x^3-4x^2+3x+2$

so that the answer is (probably) the third choice.

Whoever originally wrote this question should reevaluate their word choice...

ANSWER

The larger number is 18

<u>EXPLANATION</u>

Let x be the larger number and y be the smaller number.

Then,

$x+y=12--(1)$
