First you should write what you know since we don't know how many helmets we will use x
helmets - 5(x)
bats - 3(6x)
then write out the equation
5(x)+3(6x)=4600
then solve so first multiple 5 times x and multiply 3 and 6x
5x+18x=4600
then combine like terms which are 5x and 18x
23x=4600
then divide both sides by 23
x=200
200is the number of helmets and since there are six times the bats as helmets you multiply that by six and get
helmets=200
bats=1200
Answer:
Step-by-step explanation:
Divide both sides by 50 and you'll get x=17/50
If x is the exponent than we can take the natural log of both sides.
x(ln)50=ln(17)
Then divide ln50 on both sides
x=ln17/ln50= 0.72423228087
Because of the relatively large coefficients {9, 42, 49}, applying the quadratic formula would be a bit messy. Instead, I've chosen to "complete the square:"
9x^2 + 42x + 49 = 0 can be re-written as 9 [ x^2 + (42/9)x ] = -49
Dividing both sides by 9, we get [ x^2 + (42/9)x ] = - 49/9
Completing the square: [ x^2 + (42/9)x + (21/9)^2 - (21/9)^2 ] = -49/9
[ x + 21/9 ]^2 = 441/81 - 441/81 = 0
Then [ x + 21/9 ] = 0, and x = -21/9 (this is a double root).
I’m not sure but for Louise it’s cost $1.52 and for Thelma is $1.26 . What you basically do is divide
