Answer:
The given equation cannot be solve but can be simplified.
Step-by-step explanation:
Given equation: 5x-6y+87z = 6x+96y-867z
We can only simplify the equation, but we cannot solve because there are three unknown variables and only one equation.
To successfully solve, we requires minimum of three equations.
lets simplify it:
- first place the similar variables at one place:
5x - 6x -6y - 96y +87z +867z =0
- Now perform the respective operation to the constants:
-x-102y+ 953z =0
⇒ x +102y + 953z =0
Which is the required simplification.
Answer:
a) On <u>Friday</u> maximum number of students were absent while on <u>Saturday</u> minimum number of students were absent.
b) On Wednesday <u>135 students</u> were absent.
On Friday <u>150 students</u> were absent.
c) On <u>Monday</u> and <u>Thursday</u> same number of 130 students were absent.
Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!
5, -4. that might not be right, though
Answer:
a) £600
b) £1400
Step-by-step explanation:
a)
original price = x
reduced price = £420
reduced price is 70% of original price
Since the discounted price, £420, is 70% of the original price, x, then
70% of x = 420
0.7x = 420
x = 420/0.7
x = 600
Answer: £600
b)
original price = x
discounted price = £840
discount percentage = 40%
The original price is x, and x is 100% of the original price since 100% is the whole amount. The discount is 40% of the original price. 100% - 40% = 60%. That means the discounted price is 60% of the original price.
60% of x = 840
0.6x = 840
x = 840/0.6
x = 1400
Answer: £1400
