Andreas can type 32 words in 72 seconds. At this rate, how long would it take him to type 56 words? (

It will take Andreas 156 seconds or 2 minutes and 36 seconds to write 56 words.

Step-by-step explanation:

72 ÷ 32 = 2.25

2.25 = unit rate

2.25 × 56 = 156

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

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
