Answer:
a+4=11b
Step-by-step explanation:
Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.
for example a( b+c) = ab+ac
Therefore, applying distributive property in asked eapression
12(2a - 6b+ 8) = 21(2a−6b+8)
24a+72b+96 = 42a-126b+168
198b=18a+72
9a +36=99b
3a+12=33b
a+4=11b
Answer: 5+x
Step-by-step explanation:
Not sure if you want it in an equation but here it is: 5+x
Answer:
f(x) = -2*sqrt(x - 7 + 1)
Step-by-step explanation:
If by "statement" you mean equation, then it's pretty self-explanatory. Sorry if I'm confused though, you probably didn't list the proper choices.
Answer:
a. -6
b. +6
c. -6
Step-by-step explanation:
minus times plus times plus = -
minus times minus times plus = +
minus times minus times minus = -
1 times 2 times 3 = 6
so:
-1 times 2 times 3 = -6
-1 times -2 times 3 = +6
-1 times -2 times -3 = -6
The given data is the following:
Student Trial 1 Trial 2 Trial 3 Average
----------- -------- -------- -------- ------------
1 66.0 66.5 68.5 67.0
2 67.5 64.0 70.5 67.3
3 60.3 60.5 60.5 61.0
4 55.0 58.0 59.0 57.3
Let us check the reported averages.
Student 1:
Average = (66.0 + 66.5 + 68.5)/3 = 67.0 Correct
Student 2:
Average = (67.5 + 64.0 + 70.5)/3 = 67.3 Correct
Student 3:
Average = (60.3 + 60.5 + 60.5)/3 = 604 Incorrect
Student 4:
Average = (55.0 + 58.0 + 59.0)/3 = 57.3 Correct
Answer: Student 3
