Answer:
The answer will be y-4=-2(x+1)
Answer:
3
Step-by-step explanation:
When you divide 27 by 3 it will give you 9 and the square root of 9 gives you a perfect answer indicating that 3 is the least number that must be divided into 27
Rounding it to the tens place so your answer for 12mm is going to be 10
Answer:
Step-by-step explanation:
marked down by 1/4 of the original price.
let x represent original price
original price - 1/4 of original price = sales price
x - 1/4x = 128
4/4x - 1/4x = 128
3/4x = 128
x = 128/(3/4)
x = 128 * 4/3
x = 512/3
x = 170.666 rounds to 170.67 <== original price
==============================
I hope I am understanding this one correctly...
let x = price the store paid
x + 1/2x = 170.67
2/2x + 1/2x = 170.67
3/2x = 170.67
x = 170.67 / (3/2)
x = 170.67 * 2/3
x = 341.34/3
x = 113.78 <=== what the store paid
===========================
the difference between the discount price..I am assuming this is the $ 128 from part A.....and what the store paid....113.78...from part B..
128 - 113.78 = $ 14.22 <==
I am not completely sure about B and C......B confused me.....and if B is wrong, so is C.
Answer:
or 21.45%
Step-by-step explanation:
To find the probability that Jake will get a calculator, we simply divide the number of calculators to the number of students in the class.
Probability = 
Probability =
To find the probability in percentage form, we simply multiply the quotient of by 100
0.2142 x 100 = 21.42%
So Jack has a 21.45% chance of getting a calculator from the teacher.
