Answer:
x=60
Step-by-step explanation:
3/5x + 1/4x=51
12/20x+5/20x=51
17/20x=51
17x=1020
x=60
Double-Check:
3/5(60)+1/4(60)=51
180/5+60/4=51
36+15=51
51=51
Hope it helped!
Answer:
False.
Step-by-step explanation:
A complementary angle is an angle where two seperate angles add together for a 90 degree angle. They usually share a side, but not always.
Hello,
Let's assume a the age of Bea
b the age of her sister
This year: a+b=18
Next year (a+1)+(b+1)=(a+b)+(1+1)=(a+b)+2=18+2=20
The given equations are y= 6x^2+1 and y=x^2+4
Both the equations equal y so we can make them equal
6x^2+1=x^2+4
To bring x term on one side we subtract x^2 both sides
6x^2-x^2+1=4
5x^2+1=4
To isolate x term we subtract 1 both sides
5x^2=4-1
5x^2=3
Dividing by 5 both sides
X^2=3/5
Taking root of both sides we have:
X=±√⅗
Substituting x value to find y
When x=+√⅗=0.7745
Y= 6x^2+1
Y=6(3/5)+1
Y= 18/5+1
Y=23/5 =4.6
When x= -√⅗=-0.7745
Y= 6(3/5)+1
Y=23/5=4.6
Point of intersections are ( 0.7745,4.6) and (-0.7745,4.6)
Your starting equation is:
x/6 + 4 = 15
The first step would be to subtract 4 from both sides, to move all of the constants to the right side of the equation.
x/6 = 11
The final step is to multiply both sides by 6, to get rid of the fraction on the left side of the equation.
x = 66
Hope this helps!
