Answer:
$ 1.10
Step-by-step explanation:
p + r = 1.45....p = 1.45 - r
2p + r = 1.80
2(1.45 - r) + r = 1.80
2.90 - 2r + r = 1.80
-2r + r = 1.80 - 2.90
-r = - 1.10
r = 1.10 <=== a ruler costs $ 1.10
p + r = 1.45
p + 1.10 = 1.45
p = 1.45 - 1.10
p = 0.35 .......a pencil will cost $ 0.35
Answer:
A.
Step-by-step explanation:
Sub in the (x,y) points given into the equation to see if true ....you'll find A is the answer
Example point (3,95 ) 95 = -10.375 (3) + 126.125 ??
95 = 95 Check !
then try the other point ( 11,12) to be sure ....
Answer:
10 g^4 h^9
Step-by-step explanation:
-5gh^4 * (-2g^3 h^5)
Rewriting
-5*-2 g*g^3 h^4*h^5
When the bases are the same, we add the exponents (x^a * x^b = x^ (a+b)
There is an implied 1 if there is no exponent
-5*-2 g^1*g^3 h^4*h^5
10 * g^(1+3) h^(4+5)
10 g^4 h^9
