Directions: Solve for x.<br> Please help
aksik [14]

Answer:

Step-by-step explanation:

Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:

\frac{7}{21} =\frac{x}{18} and cross multiply to get

Someone please help me to solve this questions...​...
wlad13 [49]

Answer:

1) Event A = 2/3

   Event B = 1/2

2) 1/2

Step-by-step explanation:

1)

Event A :

No. we need on dice = 4

Total numbers on dice = 6

Hence sample space of the event = 6

P( getting 4) = 4/6 = 2/3

Event B :

A coin has a head & a tail.

Hence sample space of the event = 2

But as we need tail only ,

P ( getting Tail ) = 1/2   [ if only tossed once ]

2)

Total numbers on a die = 6

Total no. of odd numbers on die = 3 (∵ 1 , 3 & 5 are odd )

Sample space of this event = 6

P (getting an odd number) = 3/6 = 1/2

In a village the number of houses and the number of flats are in the ratio 9:5 the number of flats and the number of bungalows T
Makovka662 [10]

Answer:

Total no. of houses = 140

Step-by-step explanation:

Let there are 9x flats and 5x bungalows.

Total bungalows = 50

It means,

5x = 50

x = 10

No of flats = 9x

= 9(10)

= 90

Total houses = no. of flats + no. of bungalows

= 50+90

= 140

So, there are 140 houses in the village.

4x2 + 8x - 7 - (3x2 - X+9)​
Andreas93 [3]

Answer:

<h2>{x}^{2}  + 9x - 16</h2>

Step-by-step explanation:

4 {x}^{2}  + 8x - 7 - (3 {x}^{2}  - x + 9)

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

4 {x}^{2}  + 8x - 7 - 3 {x}^{2}  + x - 9

Collect like terms

4 {x}^{2}  - 3 {x}^{2}  + 8x + x - 7 - 9

{x}^{2}  + 9x - 7 - 9

Calculate

{x}^{2}  + 9x - 16

Hope this helps...

Good luck on your assignment...
