Answer:

x,y =3,-4

Step-by-step explanation:

// Solve equation [1] for the variable y

[1] y = 2x - 10

// Plug this in for variable y in equation [2]

[2] 3x - 2•(2x-10) = 17

[2] -x = -3

// Solve equation [2] for the variable x

[2] x = 3

// By now we know this much :

x = 3

y = 2x-10

// Use the x value to solve for y

y = 2(3)-10 = -4

Jake lives 2⅓mile from school. He decides to walk to the shop on his way home. The shop is 1⅜mile from school. A) What is the shortest possible distance from the shop to his home? B) What is the largest possible distance from the shop to his home?

Answers

Answer:

Shortest distance = 23/24

Farthest distance = 3 17/24 miles

Step-by-step explanation:

Distance of home from school = 2 1/3 miles

Distance of shop from school = 1 3/8 miles

Shortest distance possible :

(2 1/3 - 1 3/8) miles

(7/3 - 11/8) miles

L. C. M = 24

(56 - 33) / 24

23 / 24 miles

The farthest distance :

(2 1/3 + 1 3/8) miles

(7/3 + 11/8) miles

L. C. M = 24

(56 + 33) / 24

89 / 24

= 3 17/24 miles

If angle 1 = 55°, what is angle 5?
A. 55°
B. 40°
C. 35°
D. 25°

thanks ;)

Answers

It’s C because 90-55

It’s C i believe
Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

What is the best approximation of the solution to the system to
the nearest integer values?
o
(3, 4)
o
(2, 3)
O (1, 3)
o (3, 2)

Answers

Answer: (2,3)

====================================================

Explanation:

The intersection point of the two lines is where the solution point is located.

The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.

At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.

So that's how we get to (2,3)

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY

Answers

Answer:

x=2

Step-by-step explanation:

Simplify both sides of the equation.

2x−1−(−x + 3)=6−2x

(Distribute the Negative Sign)

2x−1 + −1(−x + 3)=6−2x

2x + −1 + −1(−x) + (−1)(3)=6−2x

2x + −1 + x + −3=6−2x

2x + −1 + x + −3=6 + −2x

(Combine Like Terms)

(2x + x) + (−1 + −3)=−2x+6

3x + −4=−2x + 6

3x−4=−2x + 6

Add 2x to both sides.

3x−4 + 2x=−2x + 6 + 2x

5x−4=6

Add 4 to both sides.

5x−4 + 4=6 + 4

5x=10

Divide both sides by 5.

5x/5=10/5

x=2

A field is in the shape of a trapezium.
Not to scale
210 m
190m
250m
The field produces 7200 kilograms of barley per hectare.
One hectare is 10000 m²,
Work out how many kilograms of barley the field produces.

Answers

Answer:

36,000 kg

Step-by-step explanation:

✔️First, find the area of the trapezium field:

Area of trapezium = ½(a + b)*h

Where,

a = 210 m

b = 190 m

h = 250 m

Area of trapezium = ½(210 + 190)*250

= ½(400)*250

= 200*250

= 50,000 m²

✔️Find the kg of barley that 50,000 m² field will produce:

10,000 m² (1 ha) produces 7,200 kg

Therefore,

50,000 m² will produce:

(50,000*7,200)/10,000

= 5*7,200

= 36,000 kg of barley
