Answer: 67

Step-by-step explanation:

I think this could be solved using division. 1000 / 15 is 66.66666, but I would round that to 67.

2X+15= -3x how do you work this equation

Sphinxa [80]

Answer: $x=-3$

Add 3x to both sides

$2x+15+3x=-3x+3x\\5x+15=0$

Subtract 15 from both sides

$5x+15-15=0-15\\5x=-15$

Divide both sides by 5

$5x/5=-15/5\\x=-3$

there are 124 students in the band. there are 12 more boys than girls in the band. how many boys and how many girls are in the b

kvv77 [185]

B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12

g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56

b= 56 + 12
b= 68

If f(×)=4×^2+1 and g(x)=×^2-5 find (f-g)(×)

trasher [3.6K]

Answer:

$\large\boxed{(f-g)(x)=3x^2+6}$

Step-by-step explanation:

$(f-g)(x)=f(x)-g(x)\\\\f(x)=4x^2+1,\ g(x)=x^2-5\\\\\text{Substitute:}\\\\(f-g)(x)=(4x^2+1)-(x^2-5)=4x^2+1-x^2-(-5)\\\\=4x^2+1-x^2+5\qquad\text{combine like terms}\\\\=(4x^2-x^2)+(1+5)=3x^2+6$
