Answer:
x=2
Step-by-step explanation:
5(x+3)-2=13
5(x+3)=15
x+3=5
x=2
Answer:
<QRS= (10.x - 1) = (10.6 - 1) = 59°
Step-by-step explanation:
the triangle is not accurate but drawing one is truly useful in calculating. Besides, I don't know how it is called in English but it is something about the exterior angles (maybe)
1,200(1.039)^.66666
1200(<span>1.02583386437)
$1231.00

I'm so sorry but I can't help you with this problem
: 1) If you were going to solve these, you would set them up like this.
s+p=19
7s+10p=121
among the choices, b is the only one that is equivalent to one of these equations
2) The problem looks a little confusing. If the price is per box then they easily make $275.
8b+9h=53
20*8b+30*9h=275
If it's per batch, the answer is B.
3. x^2+y^2=16
y=x+4
solve the first equation for y
y=√16-x^2
x+4=√16-x^2
(x+4)^2=16-x^2
x^2+8x+16=16-x^2
2x^2+8x=0
2x(x+4)=0
x=0 or x=-4
(be carefull i copyed and pasted the answer)
