<u><em>Answer: x=-25 and -25=x *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
multiply by -5 both sides of an equation.
(-2/5x)(-5)=10(-5)
simplify by equation.
2x=-50
divide by 2 both sides of an equation.
2x/2=-50/2
simplify by equation.
50/2=25
25*2=50
50/25=2
It changes positive to negative.
x=-25 and -25=x
Hope this helps!
Thanks!
Have a great day!
The total cost of the cab ride was $25.50. The cabbie charges $1.50 per mile the entire trip.
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation
(5x+3x)+(-32+12)=180
8x-20=180
Step 2: Add 20 to both sides.
8x-20+20= 180+20
8x= 200
Step 3: Divide both sides by 8
8x/8= 200/8
x= 25
Answer:
T (6, 5 )
Step-by-step explanation:
Using the section formula
If (x₁, y₁ ) and (x₂, y₂ ) are divided in the ratio m : n , then
(
,
) are the coordinates of the internal point
Here (x₁, y₁ ) = A (- 4, 10 ) , (x₂, y₂ ) = B (10, 3) , m : n = 5 : 2
T = (
,
)
=
,
)
=
,
)
= (6, 5 )
