Answer: They are wrong
Step-by-step explanation: x is given a value in the problem. Since x equals 4, We plug x into the equation.
y = 2(4) + 1
Y is actually equal to 9 minutes, not twelve.
Answer:
Identity property
Step-by-step explanation: because the product of any number and one is that number
Answer:
A
Step-by-step explanation:
Because when a decimal is only one number after a zero, it equals ten of whatever number it is. Since 60 is greater than 41 it is -0.6 ( -0.60 ) has more negative value than -0.41.
Answer:
74.30
Step-by-step explanation:
Let s = entry price for a student
Let t = entry price for a teacher
4s +5t = 95
6s+10t = 173
I will use elimination to solve this problem.
Multiply the first equation by -2
-2(4s +5t) = -2*95
Distribute
-8s - 10t = -190
Add this equation to the second equation to eliminate t
-8s - 10t = -190
6s+10t = 173
----------------------
-2s = -17
Divide by -2
-2s/-2 = -17/-2
s = 8.50
Now we need to find t
4s +5t = 95
Substitute s=8.50
4(8.50) +5(t) = 95
34 +5t = 95
Subtract 34 from each side
34-34 +5t = 95-34
5t = 61
Divide by 5
5t/5 = 61/5
t = 12.20
We want to find the cost for 3 students and 4 teachers
3s+4t
3(8.50) + 4(12.20)
25.50 + 48.80
74.30
ANSWER
The value of a and b are:
EXPLANATION
The expression given to us is
We square both sides of the equation to obtain
We now find the prime factorization of 648 to obtain,
We now compare the exponents on both sides of the equation to obtain,
Therefore the correct option is C
