-2^2(-5x+10)=100
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
Hi there!
[tex]-2^2(-5x+10)=100[/tex]
Solve -2^2:
[tex]-4(-5x+10)=100[/tex]
Divide both sides by -4:
[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]
Subtract 10 from both sides:
[tex]-5x+10-10=-25-10\\-5x=-35[/tex]
Divide both sides by -5:
[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]
Therefore, x = 7.

Annika borrowed a book from the library and forgot to return it on time. The library charges $0.25 per day for the first four days and $0.30 per day for all of the remaining days. If Annika had to pay the library $4.00, how many days late was her book?
please help me.
The number of days the book was late is 14 days.
The given parameters include;
let the number of days late before she returned the book = xThe following algebraic equation will be set to calculate the number of days the book was late before it was returned;
[tex]0.25(4) + (x - 4)0.3 = 40\\\\[/tex]
simplify the equation as follows;
[tex]1 + 0.3x - 1.2 = 4\\\\[/tex]
collect similar terms together;
[tex]0.3x = 4.2\\\\[/tex]
divide through by 0.3
[tex]x = \frac{4.2}{0.3} \\\\x = 14 \ days[/tex]
Thus, the number of days the book was late is 14 days.

Find how many days late was her book
The total days late is 14 days
charges per day for first 4 days = $0.25
charges per day for the remaining days = $0.30
Total amount Annika paid = $4.00
let x = number of days of the remaining days
Total amount paid = Amount paid for first 4 days + amount paid for remaining daysAmount paid for first 4 days = $0.25 × 4
= $1
Amount paid for remaining days = 0.30 × x
= 0.30x
Total amount paid = Amount paid for first 4 days + amount paid for remaining days
4 = 1 + 0.30x
4 - 1 = 0.30x
3 = 0.30x
x = 3/0.30
x = 10 days
Total days late = 4 days + 10 days
= 14 days

Range = 5
Mode = 7
Step-by-step explanation:
To find range we first need to find the highest number and the lowest number
3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8
least number = 3
highest number = 8
now substract the lowest number from the highest to get the range
= 8-3
= 5
range = 5
Mode : the most common number in the list will be our mode
7 is our mode as it came 5 time in the list
UNICORN A IS 15 TIMES OLDER THAN
UNICORN B. THE SUM OF THEIR AGES
IS 320 YEARS.
HOW OLD IS EACH UNICORN?
Answer:
Unicorn A is 300 years old
Unicorn B is 20 years old
Explanation:
15x + x = 320
16x = 320
x = 20
15 * 20 + 20 = 320
We have that Each unicorn is 20 ans 300 years receptively
[tex]A=300\\\\B=20[/tex]
From the Question we are told that
UNICORN A IS 15 TIMES OLDER THAN UNICORN B.
THE SUM OF THEIR AGES IS 320 YEARS.
Let
x=age of unicorn A
y=age of unicorn B
Therefore
[tex]x=15y....1\\\\\x+y=320.....2[/tex]
Sub (1) into 2
[tex](15y)+y=320\\\\y=20[/tex]
therefore
[tex]x=15(20)\\\\x=300[/tex]
In conclusion
Each unicorn is 20 ans 300 years receptively

what is 640 divided by 20
Answer:
640/20 is 32
hope it's helpful
When the number 640 is divided by the number 20, the result is 32.
To divide 640 by 20, we perform long division or use the concept of division as the inverse of multiplication. By dividing 640 by 20, we are essentially finding how many times 20 can be evenly divided into 640.
On Dividing 640 by 20 yields a quotient of 32. This means that 20 can be divided into 640 exactly 32 times, without any remainder.
Thus, 640 divided by 20 is equal to 32. In simpler terms, if we distribute 640 items into 20 groups, each group will contain 32 items.
