Answer:
Total price = 240
Step-by-step explanation:
a microwave cost = 200
20% of 200 = 20/100 x 200 = 40
total price = 200 plus 20% VAT = 200 + 40 = 240
Answer:
-19
Step-by-step explanation:
Rewrite the equation from highest exponent to lowest:
-19x^7-18x^6+15x^4-26x^3
Coefficients are the numbers in front of the exponent, so the leading coefficient is what is attached to the highest exponent value.
-19x^7 is the highest exponent, so -19 is the highest coefficient.
Hi :)
Let's remember some arithmetic w/ negative integers :
a+(-b)=a-b
a-(-b)=a-b
Now
8-(-9)=8+9=17
So the answer's 17
I hope this helps
For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
Answer: a system of linear inequations that represents the situation is: 
Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.
