Alex's work for the following quiz problem is as follows: Is Alex correct? if it's incorrect, what is the correct solution?
Answer:
see explanation
Step-by-step explanation:
[tex]\sqrt{10}[/tex] and [tex]\sqrt{5}[/tex] cannot be simplified as they are already in simplest form.
Note that [tex]\sqrt{10}[/tex] + [tex]\sqrt{5}[/tex] ≠ [tex]\sqrt{15}[/tex]
Thus
2[tex]\sqrt{10}[/tex] + 5[tex]\sqrt{5}[/tex] ← cannot be simplified any further

Select all equations that are also equivalent to 0.6 + 15b + 4 = 25.6. *
15b + 4 =25.6
15b + 4 = 25
3(0.6 + 15b + 4) = 76.8
15b = 25.6
15b = 21
Answer: 15b+4=25 & 15b=21
Step-by-step explanation:0.6+15b+4=25.6
0.6+4= 4.6 , 4.6+15b=25.6 Subtract from both sides 25.6-4.6= 21 4.6-4.6=0 bring down 15b Now do 21÷15b= 1.4 . So now we know b represent 1.4. 15b+4=25 Subtract 4 from both sides 25-4=21 4-4=0 There's nothing left on that side but 15b so bring down 15b in order to get rid of your variable divide it 21÷15= 1.4 On this one b also represents 1.4 . 15b=21 this equation do not have an number so just divide 21 by 15 to get rid of your variable which equals 1.4 In this equation b= 1.4 So these to equations are equivalent which is another word for equal.
The equations which are equivalent to 0.6 + 15b + 4 = 25.6.
15b + 4 = 253(0.6 + 15b + 4) = 76.815b = 21what is equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation.
Given:
0.6 + 15b + 4 = 25.6.
On solving it further
15b + 4= 25.6-0.6
15b+4=25
15b= 25-4
15b= 21
3(0.6 + 15b + 4) = 76.8
On solving
0.6 + 15b + 4 = 76.8/3
0.6 + 15b + 4 = 25.6
So, the equivalent equations are:
15b + 4 = 253(0.6 + 15b + 4) = 76.815b = 21Learn more about equation here:

Larry ran 4/5 of the way around the track before slowing down to a walk. What percent of the track did he run? *
Answer:
80%
Step-by-step explanation:
4 divided by 5 = 0.8
0.8 x 100 = 80%
The percentage Larry ran around the track = 80%
He ran 4/5 of the way around the track before slowing down for a walk.
This means he ran 4 parts of the whole 5 parts of the track. He walks the remaining 1 part around the track.
Therefore, the percentage he ran can be calculated below
% he ran the track = 4 / 5 of 100
% he ran the track = 4 / 5 × 100 = 400 / 5 = 80%
The percentage he ran around the track = 80%

If ba - cd = b, which expression represents a? show your work
Answer:
a = cd + b / b
Explanation:
ba − cd = b
[ Step 1: Add cd to both sides ]
ab − cd + cd = b + cd
ab = cd + b
[ Step 2: Divide both sides by b ]
ab / b = cd + b / b
a = cd + b / b

Let's plug in x = 2.
f(x) = x^2
f(2) = 2^2 ... replace every x with 2
f(2) = 4
----------
Now plug in x = 3.
f(x) = x^2
f(3) = 3^2 ... replace every x with 3
f(3) = 9
-----------
And x = 5 as well.
f(x) = x^2
f(5) = 5^2 .... replace every x with 5
f(5) = 25
-----------
We see that
f(2)+f(3) = 4+9 = 13
which is not equal to f(5) = 25.
So f(2)+f(3) = f(5) is false.
------------
Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.
If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.

Favian received a $100 gift card to a clothing store.
Using only the gift card, he was able to purchase n
sweaters that cost $32 each and 1 belt for $20. If there
was no tax on the sweaters and belt, which of the
following must be true?
Answer:
32n = 100 - 20
n = 2.5
he purchased 2 sweaters
Step-by-step explanation:
32n = 100 - 20
If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20
The formula for the number of sweaters will be 32n = 100 – 20.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Favian received a $100 gift card to a clothing store.
Using only the gift card, he was able to purchase n sweaters that cost $32 each and 1 belt for $20.
If there was no tax on the sweaters and belt,
Then the equation will be
32n + 1 x 20 = 100
32n + 20 = 100

Answer:

Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes
the original line: y = 5/2x + 5
The perpendicular line: y = -2/5x + b
To find b, we have to plug (-10, 5) into x and y for our perpendicular line
5 = -2/5(-10) + b
Simplify the right side
5 = 4 + b
Subtract 4 from both sides
1 = b
The final answer = y = -2/5x + 1
Micheal bought 3 footballs with a $50 bill. The cashier gave him $2.75 in change. Each football cost the same amount
What is the cost in dollars and cents of each football?
Answer:
each football cost $15.75
Step-by-step explanation:
Micheal bought 3 footballs with a $50 bill.
The cashier gave him $2.75 in change.
Each football cost the same amount
$50 - $2.75 = $47.25
$47.25 = $15.75
3 balls
therefore, each football cost $15.75
The first term of an AP is -76 and the sum of first 45 terms is -9360. Which of the following is the last term of this AP
Answer:
- 340
Step-by-step explanation:
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] ( a + l ) → a is the first term and l the last term
Here a = - 76 and [tex]S_{45}[/tex] = - 9360 , thus
[tex]\frac{45}{2}[/tex] ( - 76 + l ) = - 9360
22.5(- 76 + l) = - 9360 ( divide both sides by 22.5 )
- 76 + l = - 416 ( add 76 to both sides )
l = - 340 ← the last term in the sequence

Answer:
x = 2 log 2 / (log 5 − log 2)
x = log 4 / log(2.5)
Step-by-step explanation:
2ˣ⁺² = 5ˣ
Take log of both sides.
log(2ˣ⁺²) = log(5ˣ)
Use exponent property.
(x + 2) log 2 = x log 5
Distribute.
x log 2 + 2 log 2 = x log 5
Subtract x log 2 from both sides.
2 log 2 = x log 5 − x log 2
Factor out x.
2 log 2 = x (log 5 − log 2)
Solve for x.
x = 2 log 2 / (log 5 − log 2)
If you want, you can simplify further:
x = log 4 / log(2.5)
