Help please
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

The value of S is 11.
Step-by-step explanation:
Okay, I found this answer due to that A = S to the power of 2 right? Then, A = 121 m2, so S2 is 121 square rooted, meaning what number is multiplied the same to get 121? 11. And if you multiply 11 by 11, you get 121.

Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm

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°

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
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.

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

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.
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
10 - 2.5x > 35
I need help
Answer:
x<-10
Step-by-step explanation:
10-2.5x>35
2.5x>10-35
2.5x>-25
x>-25/2.5
x>-10
x<-10
Answer:
x < -10
Step-by-step explanation:
-2.5x > 35-10
-2.5x > 25
-2.5x > 25/-2.5
x > -10
You have to switch the sign because you divided it by negative
x<-10
