Step-by-step explanation:
Simplifying the expression
5 + 4) 2− 5 × 2
Carl's method
(5 + 4) 2− 5 × 2 -----first error was taking only 4 from the bracket and squaring it.
Instead of solving the bracket as a whole before solving outside. And once she got it wrong from the start, every other solving would be wrong
(5 + 16) − 5 × 2
21 − 5 × 2
16 × 2
32
The right method
In simplifying the expression, we must bring in Mind our Bodmas
Which means we tackle Brackets before division, then multiplication , then addition and lastly subtraction.
(5 + 4) 2− 5 × 2
Solving the bracket first we have
(9)2-5x2
Since there is no division, we move to multiplication and we can see two sites for multiplication(9 x 2 and 5x2)
18-10
Subtracting will give us 8 as our answer.

in a city 30 °/• are female and 40°/. are males . what are remaining children
Answer:
30% are children.
Step-by-step explanation:
Females = 30%
Males = 40%
Therefore, children = 100% (total) - 30% + 40%
100 - 70
30%
in a city 30 °/• are female and 40°/. are males . what are remaining children?
SOLUTION:Given,
▶️ percentage of females = 30%
▶️ percentage of males = 40%
▶️ let the percentage of children be x.
Now,
▶️ x = 100% (total population) - 30% + 40%
▶️ x = 100% - 70%
▶️ x = 30% (Children population)
ANSWER:The population % of children in a city is 30%.
select all the numbers between 80 and 100 that have exactly 4 factors, one of which is 5.
80
85
90
95
100
Answer:
90.
Step-by-step explanation:
Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.
So the product of other 3 factors should be greater than 16 and less than 20. And we can have it from 18 only. Hence the number is 90.
The numbers between 80 and 100 having factor 5 are
80, 85, 90, 95, 100
16 = [tex]2^{4}[/tex]
17 = 17
18 = 2× 3 × 3
19 = 19
20 = [tex]2^{2}[/tex] × 5
90 = 2 × [tex]3^{2}[/tex] × 5

HELP QUICK!! solve by substitution and show work please
Answer: You should solve by equal method not substitution. y=7 x=2
Step-by-step explanation: Equal value method is when two things equal each other and in this case both 3x+1 and 5x-3 equal y so they also equal each other. 3x+1=5x-3 add 3 to each sides
3x+4=5x subtract 3x from each side
4=2x divide by 2
x=2 solve for y=3x+1
y=3(2)+1
y=7
Ariel sold bags of gourmet popcorn for the school fundraiser. She sold 30 bags in two weeks, raising $112.50 for the school. How much did a bag of gourmet popcorn cost?
Answer:
3.75 dollars

Then solve.
112.50/30 = 3.75
Your answer is 3.75.
Hope this is correct, and hope it helps ^_^
Answer:
$3.75 per bag
Step-by-step explanation:
