8 = 48/6 right?

So x - 1/6 = 48/6

If you add 1/6 --> x = 49/6

<h2>X = 49/6</h2>

Isolate the x. Add 1/6 to both sides

x - 1/6 (+1/6) = 8 (+1/6)

x = 8 1/6

hope this helps

Colt1911 [192]
The case is about proportional relatioship so to slove it you have to do this.
45(V)       ?
____  x  ____
60(V)      15

45*15=675
60*?=60
675 DIVIDE BY 60=11.25
so the answer is 11.25
hope it help you

Solve the simultaneous equation y-2x+1=0 and 4x^2+3y^2-2xy=7
Lapatulllka [165]

The first equation is y-2x+1=0

y=2x-1 (Equation 1)

The second equation is 4x^{2}+3y^{2}-2xy=7 (Equation 2)

Putting the value of x from equation 1 in equation 2.

we get,

4x^{2}+3(2x-1)^{2}-2x(2x-1)=7

4x^{2}+3(4x^{2}+1-4x)-4x^{2}+2x=7

by simplifying the given equation,

12x^{2}-10x-4=0

6x^{2}-5x-2=0

Using discriminant formula,

D=b^{2}-4ac

D=25-4 \times 6 \times -2 = 73

Now the formula for solution 'x' of quadratic equation is given by:

x=\frac{-b+\sqrt{D}}{2a}  and  x=\frac{-b-\sqrt{D}}{2a}

x=\frac{5+\sqrt{73}}{12}  and x=\frac{5-\sqrt{73}}{12}

Hence, these are the required solutions.

Can someone tell me what is 8/9+3/5
I am Lyosha [343]
Okay I am going to explain to you and show you how to get the correct answer.

Fist you need to find the Greatest common factor which is 45 because 5×9=45

8/9=40/45

+3/5=27/45
__________
67/45 is reduced to 1 22/45
5 goes into 45 9 times so 3 times 7 equals 27 and 9 goes into 45 5 times so 8 times 5 equals 40 you add both numbers up and get 67. 67 can't go into 45 so you subtract 67 from 45. 45 goes into 67 1 time so that is your whole the number. 22 is left over so that is your numerator. The denominator remains the same.

7. A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the
svp [43]

Answer: 475.59 meters .

Step-by-step explanation:

The correct equation is the following:

y =-0 .02x^2 +9.5x + 5.6

For this exercise you need to use the Quadratic formula:

x = \frac{-b\±\sqrt{b^2-4ac}}{2a}

In this case you can identify that the values of "a", "b" and "c" are:

a=-0.02\\\\b=9.5\\\\c=5.6

Now you must substitute these values into the Quadratic formula and then evaluate. You get:

x=\frac{-9.5\±\sqrt{(9.5)^2-4(-0.02)(5.6)}}{2(-0.02)}\\\\x_1=475.588\\x_2=-0.588

Choose the positive one and round it to the nearest hundreth:

x_1\approx 475.59

What is the least common denominator for adding the fractions 4/15, 1/12, and 3/8
il63 [147K]
I think you want the least common multipule (exg LCM of 2,3,4 is 12)

so we find the factors and include all of them so like this

15=3 times 5
12=2 times 2 times 3
8=2 times 2 times 2

so to include all of them we include 3 2's, 1 3 and 1 5 or 2 times 2 times 2 times 3 times 5 or 8 times 15 or 4 times 30 or 120

the LCM is 120

so 4/15=32/120
1/12=10/120
3/8=45/120

add 32/120+10/120+45/120=(32+10+45)/120=87/120
