Britney paid $4.50 for two mangoes and one bag of grapes. Finn paid $9.25 for three mangoes and two bags of grapes. Britney and

docker41 [41]

B. 4.5=2m+g
f. 9.25=3m+2g

1.25=m

sub

b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g

b. 4.5=2.5+g
f. 9.25=3.75+2g

minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation

b. 2=g
f. 5.5=2g

divide both sides of f. equation by 2

b. 2=g
f. 2.75=g

2.75-2=0.75
finn paied $0.75 more for a bag of grapes

Hi, can someone please help, and possibly explain the answer please.

mr_godi [17]

Answer:

$x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}$

Step-by-step explanation:

Quadratic formula: $x=\frac{-b\±\sqrt{b^2-4ac} }{2a}$ when the equation is $0=ax^2+bx+c$

The given equation is $1=-2x+3x^2+1$ . Let's first arrange this so its format looks like $y=ax^2+bx+c$ :

$1=-2x+3x^2+1$

$1=3x^2-2x+1$

Subtract 1 from both sides of the equation

$1-1=3x^2-2x+1-1\\0=3x^2-2x+0$

Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:

$x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}$

I hope this helps!

child admission is $5.90 and adult admission is $9.10 . 175 tickets were sold for a total sales of $1282.10 . How many child tic

GenaCL600 [577]

Answer:

Child tickets are 97

Step-by-step explanation:

x + y = 175 ...............(1)

x = 175 - y

5.90x + 9.10y = 1282.10. .........(2)

5.90 (175 - y) + 9.10y = 1282.10

1032.50 - 5.9y + 9.10y = 1282.10

3.2y = 249.60

y = 249.6. / 3.2

y = 78

From equation 1

x + y = 175

x + 78 = 175

x = 175 - 78

x = 97
