38) -first you have to subtract 4-2=2
-then solve for 2^5=32
-subtract 32-20=12
-and finally multiply 12*3=36
40) -you have to solve for the numerator and denominator first
-the denominator is simple because you just have to do 2^3 which is 8
-to solve for the numerator you have to do what's in the parentheses first (3^4-7^2) which gives you 32
-the equation you should have now is 22+1^3+32 all divided by 8
-1^3 just equals 1and then you just solve for the numerator
-to solve for the numerator you have to add 22+1+32 which gives you 55 as the numerator
-since 55 cannot be divided by 8, your answer will be 55/8 or 6.875
42) -first you have to solve for the parentheses in the brackets so solve for (67-2^6) which equals to 3
-now your numerator should look like this: 2[8+(3)^3]
-you have to solve for 3^3 which is 27
-now you solve what you have left in the brackets [8+27] =35
-multiply 2*35 which gives you 70
-70 cannot be divided by 9 so your answer is 70/9 or 7.777777778
Total bill would be excluding the discount, so Deens has included the discount on the wrong side of the equation.
So: 9X = 88-25
9X=63
63/9=7
therefore Deens bought 7 shirts
Answer:
$1.94 times 11 =21.34
Step-by-step explanation:
So 5 rubber stamps cost $9.70. Your going to divide $9.70 by 5 so you get the cost of each stamp which is $1.94 each stamp. Your going to take $1.94 and multiply it by 11. You will get 21.34. :D Hope i helped you c: By the way this is the simplified version of the equation so i dont know if you want a longer version of the answer but ya! :D
