Answer:c T = 4e + 5
Step-by-step explanation:
Multiply first, then add. 12 times 7 = 84. Then add 8. 84 + 8 = 92.
Answer:
b=k3+24k2−3700k
r=(k3−5k2+3k−5)((−k)(4))
87(|k+1|)+2088
Step-by-step explanation:
Let's note the information.
This is what we know:
Every buttons came in packages of 30 per student.
Every bookmark came in packages of 50 per person.
Know, we need to do some multiplying.
30 x 400 & 50 x 400
Now solve.
30 X 400 = 12000.
So we now know that they have an estimated 12000 buttons total.
Now, we find x for bookmarks.
50 x 400 = 20000
That means total that estimated that 20000 bookmarks will be given.
Let’s choose the first one, and do the proportions.
x/30 = 90/100
Cross multiply and you have
100x = (30)(90)
100x = 2700
x = 27
And the fourth one: multiply by the decimal equivalent of the percent.
90% = 90/100 = 0.9
0.9 x 30 = 27
You chose these because your “online tutor” finds them easiest to explain XD
