Step-by-step explanation:

Answer:

A 140

Step-by-step explanation:

Mark the center of the circle as O. It's given that

∠IOJ = 70°

∠JOK = 70°

from the drawing it looks like HOI, IOJ and JOK are supplementary angles, which means that they add up to 180°

∠HOI + ∠IOJ + ∠JOK = 180°

∠HOI = 180° - ∠IOJ - ∠JOK

∠HOI = 180° - 70° - 70°

∠HOI = 40°

∠HOI and ∠KOL are cross angles, therefore ∠HOI = ∠KOL = 40°

Since ∠HOL and ∠KOL are supplementary angles

∠HOL = 180° - ∠KOL

∠HOL = 180° - 40°

∠HOL = 140°

Help please

Answers

Answer:

x = 1 or -5/2

Step-by-step explanation:

-2x^2 - 3x + 5 = 0

multiply all through by -1

2x^2 + 3x - 5 = 0

....... 2x^2 × 5 = 10x^2 = +5x × -2x

(2x^2 + 5x)-(2x - 5) = 0

x(2x + 5) - 1(2x + 5) = 0

x - 1 = 0 or 2x + 5 = 0

x = 1 or 2x = - 5

x = 1 or -5/2

A number line can represent positions that are north and south of a truck stop on a highway. Decide whether you want positive positions to be north or south of the truck stop.

The truck stop
5 miles north of the truck stop
3.5 miles south of the truck stop

Answers

Answer:

The northern position would be positive while the southern position would be negative.

Step-by-step explanation:

Imagine 0 as the truck stop. North would be above the truck stop, while south would be below it.

On a number line, anything above 0 is a positive number. Anything below 0 is a negative number.

Therefore, the northern position would be positive while the southern position would be negative.

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

Ashley opened a lemonade stand on her street. It costs her $12.50 to buy the supplies each day, and she sells lemonade for $2.50 a cup. If she wants to make at least $200.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Ashley needs to sell? Input your answer as a whole number.

Answers

Answer:

x= 75

Step-by-step explanation:

Subtract sales - expenses

200 - 12.5 = 187.5

2.5x = 187.5

Divide by 2.5 on both sides

187.5/2.5

x = 75

Solve the system of equations – 5x + y = 56 and x + y = -4 by combining the
equations.

Answers

Answer:

Your solution is (-10, 6).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-5x + y = 56

x + y = -4

Let's change the second equation into one with one variable on each side.

y = -x - 4

Now, plug this into your first equation.

-5x + (-x - 4) = 56

Distribute the + sign.

-5x - x - 4 = 56

Combine the like terms.

-6x - 4 = 56

-6x = 60

Isolate x by dividing both sides by -6.

x = -10

Now plug this back into either equation.

-10 + y = -4

Add 10 to both sides to find y.

y = 6

Your solution is (-10, 6).

Check this by plugging in these values into the equation you have not checked yet.

-5(-10) + (6) = 56

50 + 6 = 56

56 = 56

Your solution is correct.

Hope this helps!

Answer:

x=-10; y=6

Step-by-step explanation:

combine the equations:

-5x + y + x + y = 56 +(-4)

-4x + 2y = 52

add 4x to each side

2y=52+4x

divide by 2

y=26+2x

now substitute 26+2x for y in the second equation:

x + 26 + 2x = -4

3x + 26 = -4

3x = -30

x = -10

therefore y = 6

-4x – 6 = -3.8 - 3x – 10​
