First, write it as an equation
2.50+3x=5.05
Next, subtract 2.50 from both sides
2.50-2.50+3x=5.05-2.50
3x=2.55
Divide 3 on both sides
3x/3=2.55/3
x=0.85
The cost of a bag of chips is 0.85
hope i helped :D
Answer:
22.919 or 23 degrees
Step-by-step explanation:
Use the theta or x in place of the usual angle. the lengths are adjacent and hypotenuse (a/h) so you use cosine. cos(x)=35/38 or cos(θ)=35/38
Answer:
{7, -2}
Step-by-step explanation:
6x-7y=2
2x+3y= -10
multiply the second one by -3
6x-7y=2
-6x-9x=30
-16y=32
y= -2
2x - 6 = -10
2x= -4
x= -2
Answer:
-3 does not belong because it is not an algebraic expression unlike the others.
