Zak drank 21 cups of water every week. How many ounces of water did Zak
drink every week?

1 cup = 8 ounces

21 x 8 = 168

168 ounces

Step-by-step explanation:

168

Step-by-step explanation:

1 cup equals 8 fluid ounces

Just multiply 21 by 8 and you get your answer

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
