Find x and y for the following problem.

Mathematics
1 answer:
Luba_88 [7]3 years ago
8 0

Answer:

x = 5/4

y = 7/4

Step-by-step explanation:

The smaller triangle and the larger one are similar, so the sides are proportional.

(x+5)/5 = 10/8

x/5 + 1 = 1/4 + 1 . . . . . divide it out

x/5 = 1/4 . . . . . . . . . . .subtract 1

x = 5/4 . . . . . . . . . . . . multiply by 5

___

For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...

y = 7/4

The sum of three consecutive odd numbers is 123 what is the smallest of the three numbers
Inga [223]

Answer:

39

Step-by-step explanation:

Let the three consecutive odd numbers be:

x+2, x+4, x+6.

The sum of the consecutive numbers is 123 i.e

x+2 + (x+4) + (x+6) = 123

x + 2 + x + 4 + x + 6 = 123

3x + 12 = 123

Collect like terms

3x = 123 — 12

3x = 111

Divide both side by the coefficient of x i.e 3

x = 111/3

x = 37

Now let us find the value of the three odd numbers. This is illustrated:

1st : x + 2 = 37 + 2 = 39

2nd : x + 4 = 37 + 4 = 41

3rd : x + 6 = 37 + 6 = 43

The smallest of the three consecutive odd numbers is 39

How do you solve this?
Law Incorporation [45]
Find the soluiton

2x+2y=16
3x-y=4

x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)

obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work

2 is the same as the first except both euations are just doubled

What is the cost of buying 10 tickets? <br> what is the unit rate?
Pepsi [2]

Answer:

This depends on the price of how much the tickets cost in total so if the 10 tickets cost $10 dollars then the unit price would be $1

Step-by-step explanation:

You need to divide the total number by the number 10 and then that would be your unit price.

The data below shows the points scored and minutes played by six basketball players during the 2004-2005 season. The least squar
k0ka [10]

We assume data and prediction as question is incomplete

Answer and Step-by-step explanation:

Least squares regression line equations are used to model the relationship that exists between two variables, dependent and independent variables. The equation has the form y=a+bx where y is the dependent variable and x is independent variable, a is a constant and is the y intercept and b is the slope of the line. This relationship is then used to predict future outcomes.

Given that data for 2004-2005 for the basketball players are :

James- 20 points

John- 30 points

Chris- 50 points

Dave-15 points

Donaldson- 32 points

Richard -40 points

We predict the scores/points for James (for example) for the following year using the equation of the regression line y=0.79x+1544

We substitute his points x=20 I'm the equation:

Y=0.79*20+1544

=1599.8

The predicted value is 1599.8
