Answer:
#1) 4 x 3 - 1 is less than or equal to 11 (it's equal). 4 x 3 - 1 < 11 is not true because 11 is not less than 11.
Step-by-step explanation:
#2) 8x + 1 = 57 --- subtract 1 from both sides
8x = 57 - 1
8x = 56 -- divide both sides by 8
x = 7.....any other value for x will not work
In this equation x=-1/15 or negative one fiftenth.
Answer: The required expression she is on after d days is 
Step-by-step explanation:
Since we have given that
Page number at which she is = 88
Number of pages she will read every day = 20
Let the number of days be 'x'.
According to question, it becomes
Hence, the required expression she is on after d days is
Answer:
answer is 90 hr for question 1
Step-by-step explanation
48 hr 8 liter
? 15 liter
so what ur going to do is u criss-cross when u do u multipy 48 with 15 and 8 with "?" when u multiply 48 with 15 u get 720 and when you multiply 8 with "?" u get 8?
so it will look like this
720= 8?
let make "?" an "x" for a better understanding. so the reason we are making it an "x" is because we dont know the amount of hr it takes for 15 liters of water to leak.
let go back to the calculation.
so it will look something like this
720 = 8x
exactly the same thing but we made "?" an"x"
so now we divide both sides with 8. why? because we need "x" alone and want 8 to disappear
so when u divide both sides with 8 it will look something like this
780/8 =x
so when u divide 780 with 8 u get 90. so what does that mean? it means it takes 90 hr for 15 liters of water to leak.
do you understand?
