It would be Answer C because you would just do 90 × 0.05 (<- always in decimal form). Which the answer is 94.5 or $94.50. The $35 is just extra information. Hope this helped you!
To do linear equations, basically, just imagine it with an equals sign. It is pretty much the same as normal algebra, so it's not too confusing.
An example of a linear equation is 3x - 7 = 11
with this, your objective is to get 'x' on its own and to do this, do inverse operations (the opposite to what is actually done)
For instance, to get '3x' on its own, you must add 7.
So do this for both sides to give you
3x = 18
Yeah?
Now you must get 'x' on its own. It currently has 3 x's at the moment, so you must divide it by 3 to give you one 'x'. A rule with these - what you do to one side you must do to the other.
So this means that if you divide 3x by 3, you must divide 18 by 3.
This leaves you with x = 6.
Slope: 7 given point: (1,8)
y = 7x + b step 1 - plug in the slope in the formula
8 = 7(1) + b step 2 - plug in the given point
8 = 7 + b step 3 - simplify the expression
b = 1 step 4 - solve for b
y = 7x + 1 step 5 - plug in b
formula: y = 7x + 1
Answer:
8(6-x)
Step-by-step explanation:
factor out an 8
8*6 -8*x
8(6-x)
Hello from MrBillDoesMath!
Answer:
1 cubic inch.
Discussion:
If each side of the sugar cube is 1, the volume, which is the product of the length, width, and height, equals
1 * 1 *1 =
1 cubic inch.
Thank you,
MrB
