30 miles/hour * x hours= 40 miles/hour * (x-4) hours
Distribute the 40, so you get
30x=40x-160
Subtract 40x from both sides
-10x=-160
Divide both sides by -10
x=16
They drove 16 miles
the answer to 60 cm + 40 cm is equal to 100 cm
Answer:
13 , 6.
Step-by-step explanation:
A equation is given to us and we need to find out the value of x . The given equation to us is ,
Cross multiply ,
Squaring both sides ,
Simplify the whole square ,
Add 3 and subtract x on both sides ,
Simplify ,
Split the middle term of the quadratic equation,
Take out common ,
Take out ( x -13 ) as common ,
Equate both factors to 0 ,
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>x</u><u> is</u><u> </u><u>1</u><u>3</u><u> </u><u>or </u><u>6</u><u> </u><u>.</u>
Answer:
the first one and the last one
Step-by-step explanation:
the other 2 have numbers above 1.
For the answer to the question on w<span>hat is the equation of the quadratic graph with a focus of (5, 6) and a directrix of y = 2?
</span>the vertex = (5,4)
<span>p = 2 </span>
<span>4*2(y-4) = (x-5)^2 </span>
<span>y = (1/8)(x-5)^2 + 4
</span>
I hope my answer helped. Have a nice day!
