Answer:
x = 35 , y = 72.5
Step-by-step explanation:
(a)
x and 35° are vertical angles and are congruent, then
x = 35
(b)
y. y and 35 lie on a straight line and sum to 180°, that is
y + y + 35 = 180
2y + 35 = 180 ( subtract 35 from both sides )
2y = 145 ( divide both sides by 2 )
y = 72.5
The expression that is a factor of 3y2+14-24 is 3y^2-10.
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
Answer:
<h2><em><u>
a) 7d - 16</u></em></h2><h2><em><u>
b) 7(d - 16)</u></em></h2>
Step-by-step explanation:
Question A:
Step 1. The product of 7 and d is = 7d.
Step 2. Then the next part is separated by a comma.
Step 3. This leads to the influence of the idea that 7d is subtracted by 16.
<em><u>Step 4. This concludes that the answer is 7d - 16.</u></em>
Question B:
Step 1: The product of 7 concludes that 7 is alone.
Step 2: The separation of and shows that the part after and is together.
Step 3: If it is together, we can conclude it goes in parentheses.
Step 4: If it is in parentheses, it means the number 7 is being distributed.
<em><u>Step 5: This concludes the answer is 7(d - 16).</u></em>
<em><u></u></em>
