Three times the sum of two numbers is 15. One of the numbers is 9 more than one-third of the other number.
a. How can you use a system of equations to find the two numbers?
b. What are the two numbers? Show your work.

Answers

Answer:

8, - 3

Step-by-step explanation:

one number is x, the other is y

x = 1/3y + 9

=> (1/3y + 9 + y) × 3 = 15

=> y + 27 + 3y = 15

=> 4y = 15 - 27

=> 4y = - 12

=> y = - 3

x = 1/3(- 3) + 9 = 8

The answer is a: 0.59.

The answer would be A. 0.59.

Tenths: .5
Hundredths: . 8

Answer:

m∠WXY = 111°

Opposite angles of an inscribed quadrilateral are supplementary.

m∠WXY = 180° -m∠WZY

m∠WXY = 180° -69°

m∠WXY = 111°

so we have 3 rectangle

recall that,

[tex] \displaystyle \: A _{ \text{ rect}} = l \times w[/tex]

rectangle-1:

the width of the rectangle is 10m

and the length is 12+5=17m

so the area is

the width is 3 m

[tex] \displaystyle \: A _{ \text{ rect - 2}} = 27 \: {m}^{2} [/tex]

A group of hikers begins a trip with 30 pounds of food per hiker. They will eat a total of 12 pounds of food a day. If there are 7 hikers, which equation can be used to find y, the amount of food remaining after x days? F) y = 12x + 30 G) y = -7x + 84 H) y = 12x + 210 J) y = 30x-12

Answers

Given:

Food = 30 pounds of food per hiker.

Food consumption = 12 pounds of food a day.

No. of hikers = 7

To find:

The equation for the given situation.

Solution:

Let x be the number of days and y be the amount of remaining food.

Total amount is the product of number of hikers and food per hiker.

[tex]\text{Total food}=7\times 30[/tex]

[tex]\text{Total food}=210[/tex]

Food consumption of one day = 12 pounds

Food consumption of x days = 12x pounds

Now,

Remaining food = Total food - Food consumption of x days

[tex]y=210-12x[/tex]

[tex]y=-12x+210[/tex]

Therefore, the required equation is [tex]y=-12x+210[/tex].

Note: Option C is correct if there is -12 instead of 12.

Miguel drives 200 meters up a hill that makes an angle of 7 degrees with the horizontal ground. To the nearest tenth of a meter, what horizontal distance has he covered? (Only round your answer once)

Answers

Answer:

Step-by-step explanation:

The hypotenuse is 200 meters.

The angle making the ground and the Hypotenuse is 7 degrees.

The trig relationship needed is the cosine.

Cos(7) = x / 200 Multiply both sides by 200

200*cos(7) = x

200* 0.9925 = x

x = 198.51

What is the solution?

Answers

Answer:

y = 26.2857143 or 184/7 or 26 2/7

x = -13.7142857 or -96/7 or -13 5/7

Step-by-step explanation:

-5x + 5y = 40

-x + y = 40

x = -40 + y

substitute x for -40 + y

4(-40 + y ) + 3y = 24

-160 + 4y + 3y = 24

7y = 184

y = 26.2857143 (?)

x = -40 + 26.2857143

x = -13.7142857
