Answer:
<h3>5x</h3>
Step-by-step explanation:
7x-6x+4x ← <em>(Add and subtract elements to the numbers from left to right.)</em>
<em />
7-6+4
PEMDAS- (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.
7-6+4 ← (Add & subtract.)
7-6=1
1+4=5
= 5x
5x, which is our answer.
Answer:
The simpler way is:
SP = 0.85*RP
Step-by-step explanation:
Suppose that we have a given amount A. and now we take a given percentage, X%, off.
The new amount will be:
New amount = A - (X%/100%)*A = A*(1 - X%/100%)
This is the general formula.
In this case, we know that the store has advertised 15% off, then we have X% = 15%
Then if:
SP = sales price
RP = regular price
We will have the equation:
SP = RP - (15%/100%)*RP = RP - 0.15*RP
This is what Jill found, but if we use the general equation above, we will find that:
SP = RP*(1 - 15%/100%) = RP*(1 - 0.15) = RP*0.85
So we just need to multiply the regular price by 0.85 to get the sales price.
divide total miles by time:
157.5 / 2.5 = 63 miles per hour
Answer:
Option A is the right answer.
146-4b = 122-1b
Reason: vertical angles
Answer:
I think what you meant to say is "If a triangle has 2 sides that are 4 cm and 20 cm, what are the possible lengths of the third side?"
Basically, when given 2 sides of a triangle, the third side must be GREATER than the DIFFERENCE of the other 2 sides and LESS than the SUM of the other 2 sides.
difference = 16 cm
sum = 24 cm
So, the third side must be greater than 16 cm and less than 24 cm
