Assuming that you ment- (18*9)/3d where d=3 you would follow PEMDAS-
Parentheses
Exponents
Multiplication-Division (in order from right to left)
Addition-Subtraction (in order from right to left)
1. Parentheses- (18*9)=162
2. Solve your variables- 3d (3*3)=9
Giving you- 162/9
3. Solve-162/9=18
B.<span>Adding 15 to both sides of the equation.
A. Adding 8x to both sides wouldn't cancel anything out.
B. Adding 15 to both sides will cancel out 15 making it easier to solve for x.
C.Adding 3 to both sides will not cancel anything out.
D. Adding 2x to both sides won't cancel anything out. </span>
as AB || DE then
angle BAE = angle AED
so angle AED = 70
as AD = AE then
angle AED = angle ADE = 70
now in a triangle
angle DAE + Angle ADE + angle AED = 180
angle DAE + 70 + 70 = 180
angle DAE = 180 - 140 = 40
The bookstore is on sale and they offer the following prices to the following items: => books is equals to 3 dollars => magazines costs 2.50 dollars.Now, Jam were able to spend 16 dollars in total in buying 6 books and x number of magazines. => Let's find out how many did Jam bought. => he bought a total of 6 books and magazine.=> Let's analyze how many magazines and how many books will he need to buy in order to get 16 dollars in total=> 4 magazines * 2.5 dollars = 10 dollars=> 2 books * 3 dollars = 6 dollarsin total 16 dollars.<span>
