Answer:
5. The answer is 2
6. Her error is that she was supposed to subtract 16 minus 12 instead of 12 minus 2.
Step-by-step explanation:
For number 5 all I did was solve.
12 + (25 - 5^2) - 2 =
12 + 0 - 2 =
12 - 2 = 10
10 ÷ 5 = 2
So, for number 5 the answer is 2.
For number 6, you should know that when there are only plus and minus signs you solve from left to right.
She instead put parentheses where there shouldn't of been, and because of that she is wrong.
Hope this helps! :)

Ali drove 585 miles in 9 hours.
At the same rate, how many miles would he drive in 13 hours?
Answers
Answer:
845 miles
Step-by-step explanation:
First let us find the speed ( rate ) using the below formula.
[tex]\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}[/tex]
[tex]\sf Speed=\frac{585 \:miles}{9 \:h}[/tex]
[tex]\sf Speed=65\:miles\: per\: hour[/tex]
They also said that, at the same speed he traveled for 13 hours.
So, now we have to find the distance.
For that, you can use the same formula by making the distance as the subject.
Let us find it now.
[tex]\sf Distance \:\:travellled=Speed\:*\:Time\:\:Taken\\\\\sf Distance \:\:travellled=65\:*\:13\\\\\sf Distance \:\:travellled=845 \:miles[/tex]

Answers
Answer:
Step-by-step explanation:
Simplifying
14 + -3z = 0
Solving
14 + -3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, and all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + -3z = 0 + -14
Combine like terms: 14 + -14 = 0
0 + -3z = 0 + -14
-3z = 0 + -14
Combine like terms: 0 + -14 = -14
-3z = -14
Divide each side by '-3'.
z = 4.666666667
Simplifying
z = 4.666666667

Due to the demand of their chicken sandwiches, Popeyes decided to change the price from $2.29 to $2.59. Express this change as a percentage.
A-12% increase
B-12% decrease
C-13% increase
D-88% increase
Answers
Answer: C
Step-by-step explanation: You can use the percent error formula if you know it or just do:
value 2 - value 1
x 100 = percent
absolute value of value 1
The correct option C-13% increase. The price of the chicken sandwiches percentage increased by 13%.
Explain the term percentage change?Finding the differences between the two values in such a time series, dividing the difference by the initial value, then multiplying by 100 are used to determine the percentage change here between two values. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.For the stated question;
Original price of the chicken = $2.29
Increased price of the chicken = $2.59.
Let x be the percentage increase:
Thus,
2.29 + x% of 2.29 = 2.59
2.29 + 2.29x / 100 = 2.59
229 + 2.29x = 259
2.29x = 259 - 229 = 30
x = 30 / 2.29 = 13.1
x = 13 % (approx)
Thus, the price of the chicken sandwiches increased by 13%.

What is the N in 0.5w + 15 =20
Answers
Answer: 10
Step-by-step explanation:
I’m not sure where the N fits into the equation, but if you are finding the amount that w holds, 10 is correct.
Reverse the equation: 20=15+.5w
Now move .5 over and do 20-15 which equals 5.
.5w=5
5 divided by .5 gives you the answer of 10. 10•.5=5 which means 10 is your answer!
Answer:
w = 10
Step-by-step explanation:
Rectifying mistake in question,
→ Value of w in 0.5w + 15 = 20.
Given equation,
→ 0.5w + 15 = 20
Now the value of w will be,
→ 0.5w + 15 = 20
→ 0.5w = 20 - 15
→ 0.5w = 5
→ w = 5/0.5
→ [ w = 10 ]
Hence, the value of w is 10.
