I'm not doing your math homework, this is to help you learn and pass your test :) I will however show you a trick. ask your self this... "What can i factor out of 4x that i can also factor out of 8, which this would be 4. Now what you do if you divide everything by 4
4x/4 = x
8/4 = 2
so 4(x+2) is 4x+8 fully factored, NOW to check, use the distributive property, Multiply 4 back into x+2
4*x = 4x
4*2 = 8
so 4(x+2) = 4x+8
Answer:
Step-by-step explanation:
7^8*7=
5764801 * 7= 40353607
A. 7^3*7^3= 343*343= 117649 <--- not the answer
B. 7^18/7^9= 40353607 <---- right answer
C. (7^3)^3= 343^3= 40353607 <------ right answer
D. 7^5+7^4= 16807+2401= 19208 <---- not the answer
E. 7^5*7^4= 16807*2401= 40353607 <---- right answer
Answer:
9/11
Step-by-step explanation:
Well we know there are 55 students in total and only 45 of them can either play a string or brass instrument.
So 45/55 is 9/11
Thus probably is 9/11 of a randomly selected student who plays either a string or brass.
Answer:
The required expression is 
.
The value of the expression when y=20 is 2.
Step-by-step explanation:
Consider the provided phase.
3 less than the quotient of a number y and 4
The quotient of a number y and 4 can be written as: 
Now 3 less than the quotient of a number y and 4 can be written as:
Hence, the required expression is .
Now evaluate when y=20.
Substitute y=20 in above expression.
Hence, the value of the expression when y=20 is 2.
Answer:
25
Step-by-step explanation:
144/60 = 2.4
60/2.4 = x
x = 25
