1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.
2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.
3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.
In conclusion:
Triangle=3
Square=-2
Star=7
Answer:
a = -2
Step-by-step explanation:
-3a + 8 = 14
14 - 8
= 6
-3a = 6
6/-3
= -2
a = -2
Please give me brainliest :)
Step-by-step explanation:
crossmultiply and divide both sides by the co efficient of x

Answer:
71.447296
Step-by-step explanation:
The sequence is geometric with first term 100 and common ratio -0.4. Then the sum of n terms is ...
Sn = 100(1 -(-0.4)^n)/(1 -(-0.4))
and the sum of 9 terms is ...
S9 = 100(1 -(-0.4^9))/(1.4) = 71.447296
