2 / 4 = 1 / 2 = 9 / 18 ;
2 / 9 = 4 / 18 ;
9 > 4 ;
9 / 18 > 4 / 18 ;
Then, 2 / 4 > 2 / 9 .
To grandparents house :
140/56 = 2.5 hours
Return trip :
140/50 = 2.8 hours
Total time : 2.8+2.5 = 5.3 hours
Answer:
c
Step-by-step explanation
Factoring: 2x3-5x2+7x-6
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 7x-6
Group 2: 2x3-5x2
so its c
Pull out from each group separately :
Group 1: (7x-6) • (1)
Group 2: (2x-5) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Step-by-step explanation:
let w be the cost of a bottle of water and p be the cost of a bag of pretzels
"2 bottles of water and 3 bags of pretzels is $7.05" can be written as
2w + 3p = 7.05 ------------- eq.1
"The cost of a bag of pretzels is $1.35" can be written as
p = 1.35 ------------- eq 2
Together, eq 1 and eq 2 make up your system of equations
To solve, take eq 2 and substitute this value int eq 1
2w + 3 (1.35) = 7.05
2w + 4.05 = 7.05
2w = 7.05 - 4.05
2w = 3
w = 1.5
Hence the cost of a bottle of water is $1.50
