Answer:
y=17
Step-by-step explanation:
So the shape is a square, which means 1 is equal to 90 degrees. So, 4y+22=90
When you solve, you get 17:
4y=68
y=17
-2 + 3b = 5b - 2(2b + 3) Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6 Combine like terms
-2 + 3b = b - 6 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6 Combine like terms
-2 + 2b = -6 Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2 Combine like terms
2b = -4 Isolate b by dividing both sides by 2
b = -4/2 = -2
Answer b = -2
Step-by-step explanation:
340=8min
850=?(x)
340x=850×8
340x=6800
x=6800/340
x=20min
so..the teachertook 20 minute to print 850 copies
18.6 seconds ...................
4:48 minus 4:00 = 48 min
Time in hours is +48%2F60+=+4%2F5++ hrs
+40+=+r%2A%284%2F5+%29+
+r+=+%285%2F4%29%2A40+
+r+=+50+ mi/hr
+40+=+50%2A%284%2F5%29+
