5 x 7 because if 5 is the width is 25 then 18 minus that is 7 and 7x5 = 35
Answer is C weak negavite
weak, because as the value became smaller that 1 the correlation weakens. negavite because it is a negative value (-0.23)
Answer:
360 in ^3
Step-by-step explanation:
The volume is given by
V = l*w*h
= 8 * 5 * 9
= 360 in ^3
x+y=8 and 25x+10y=170 are the linear equations.
x+y≤8 and 25x+10y≤170 are the inequalities.
Step-by-step explanation:
Given,
Worth of coins = $1.70 = 1.70*100 = 170 cents
Number of coins = 8
1 quarter = 25 cents
1 dime = 10 cents
Let,
x represent the number of quarters
y represent the number of dimes
1. Write an equation to represent the amount of coins Karen has.
x+y = 8
2.Write an equation to represent the value of the coins Karen has.
25x+10y=170
x+y=8 and 25x+10y=170 are the linear equations.
For inequalities, the amount cannot increase number of coins and worth but it can be less, therefore,
x+y≤8
25x+10y≤170
x+y≤8 and 25x+10y≤170 are the inequalities.
