Mathematics
1 answer:
Arlecino [84]3 years ago
5 0

Answer:

x = -4 , x = -1

Explanation:

Multiply by x on both sides to get rid of fraction

x(x + 4/x) = x(-5)

x^2 + 4 = -5x

x^2 + 5x + 4 = 0

Factor

(x+4)(x+1) = 0

x = -4 , x = -1

Marie uses 2.3 oz of nuts for each bag of trail mix she makes. She uses 27.6 oz of nuts in all. How many bags of trail mix does
anastassius [24]
We are given that each bag of trail mix consumes 2.3 oz of nuts. To know the amount of bags of trail mixes that can be made using 27.6 oz of nuts, all we have to do is cross multiplication as follows:
2.3 oz of nuts ............> 1 bag of trail mix
27.6 oz of nuts ...........> ?? bag of trail mix

number of bags = (27.6*1) / 2.3 = 12 bags

Point D is in the interior of ZABC, m ABC = 10x - 7, m_ABD = 6x + 5, and m DBC = 36. What is m ABD?
mestny [16]

Answer:

<h3>77</h3>

Step-by-step explanation:

If Point D is in the interior of <ABC, then <ABD+<BDC = <ABC

Given

<ABC = 10x - 7,

<ABD = 6x + 5

<DBC = 36

Substituting the given parameters into the formula above;

ABD+<DBC = <ABC

6x + 5+ 36 = 10x-7

6x+41 = 10x-7

collect like terms

6x-10x = -7-41

-4x = -48

divide both sides by -4

-4x/-4 = -48/-4

x = 12

To get <ABD, we will substitute x = 12 into the expression <ABD = 6x + 5

<ABD = 6(12)+5

<ABD = 72+5

<ABD =77

Hence the value of <ABD is 77

(Teaser) The total number of sides in two regular polygons is 13, and total number of diagonals is 25. How many sides are in eac
NISA [10]

Answer:  

T he two polygons have 8 sides and 5 sides.  

Step-by-step explanation:

A purely algebraic solution seems as if it would be very messy. Use trial and error, along with the formula for the number of diagonals in a n-sided polygon.

number of diagonals in a polygon with n sides: n(n-3)/2

10 sides and 3 sides: 10(7)/2 + 3(0)/2 = 35+0 = 35 nope....

9 sides and 4 sides: 9(6)/2 + 4(1)/2 = 27+2 = 29 nope....

8 sides and 5 sides: 8(5)/2 + 5(2)/2 = 20+5 = 25 yep!
