Answer:
1. 5m+4=7m+6
Step 1: Subtract 7m from both sides.
5m+4−7m=7m+6−7m
−2m+4=6
Step 2: Subtract 4 from both sides.
−2m+4−4=6−4
−2m=2
Step 3: Divide both sides by -2.
[tex]\frac{-2m}{-2} = \frac{-2}{2}[/tex]
m=−1
_______________________________
2. −5x+3=2x−1
Subtract 2x from both sides.
−5x+3−2x=−1
Combine −5x and −2x to get −7x.
−7x+3=−1
Subtract 3 from both sides.
−7x=−1−3
Subtract 3 from −1 to get −4.
−7x=−4
Divide both sides by −7.
x= [tex]\frac{-4}{-7}[/tex]
[tex]Faction \frac{-4}{-7}[/tex] can be simplified to [tex]\frac{4}{7}[/tex] by removing the negative sign from both the numerator and the denominator.
x= [tex]\frac{4}{7}[/tex]
_____________________________
3. 5t−3=3t+5
Subtract 3t from both sides.
5t−3−3t=5
Combine 5t and −3t to get 2t.
2t−3=5
Add 3 to both sides.
2t=5+3
Add 5 and 3 to get 8.
2t=8
Divide both sides by 2.
t= [tex]\frac{8}{2}[/tex]
Divide 8 by 2 to get 4.
t= 4
___________________________
4. 3y−55=42y
Subtract 42y from both sides.
53y−55−42y=0
Combine 53y and −42y to get 11y.
11y−55=0
Add 55 to both sides. Anything plus zero gives itself.
11y=55
Divide both sides by 11
y= [tex]\frac{55}{11}[/tex]
Divide 55 by 11 to get 5.
y=5

If a certain medicine cures 85% of the people who take it,what is the probability that, if 6 people take the medicine, exactly 4 will be cured?
Answers
Answer:
if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.
Step-by-step explanation:
Given that a certain medicine cures 85% of the people who take it.
As 6 people take the medicine, we need to determine how many will be cured.
As
85% = 85/100 = 0.85
All we need is to multiply 6 with 0.85.
i.e. 6 × 0.85 = 5 (Rounded to the nearest 1 or the Ones Place)
Thus, if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.

Buckeye truck rentals has a daily rate of $59.99 plus $0.34/mile. Goodyear truck rentals has the same size truck for 58.95 plus $0.36/mile. At how many mile will the cost be the same?
Answers
Answer:
52 miles
Step-by-step explanation:
Step one:
given data
Buckeye truck rentals
daily rate of $59.99
plus $0.34/mile
let the number of miles be x
and the total charge be y
so
y= 0.34x+59.99---------------1
Goodyear truck rentals
daily rate of 58.95
plus $0.36/mile
let the number of miles be x
and the total charge be y
so
y= 0.36x+58.95---------------2
Step two:
Equate the two equations above to find x
0.34x+59.99=0.36x+58.95
collect like terms
59.99-58.95=0.36x-0.34x
1.04=0.02x
divide both sides by 0.02
x= 1.04/0.02
x=52 miles

tenth, if necessary. Make sure you show all steps needed to solve the
problem.
Answers
Answer:
[tex]a=9[/tex]
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex]) to find what a is. The steps are shown below:
Steps (variables a, b, and c are in italics):
-You can rearrange the formula from the Pythagorean Theorem, which is[tex]a^{2} +b^{2} =c^{2}[/tex] to only get a because we want to know what a is.
Rearranged: [tex]a=\sqrt{c^{2}-b^{2} }[/tex] or [tex]a=-\sqrt{c^{2}-b^{2} }[/tex] It has to ways/options for a because when finding the square root of a number, it can be either positive or negative. But in this problem, it’s going to be positive because we’re finding the length of something.
-Since we know what c and b are, you can plug them into the new formula:
[tex]a=\sqrt{15^{2}-12^{2} }[/tex]
-Simplify it:
[tex]a=\sqrt{225-144}[/tex]
-Subtract inside the radical:
[tex]a=\sqrt{81}[/tex] Then simplify it to get [tex]a=9[/tex].
You can check your answer by putting a back into the original Pythagorean Theorem formula ([tex]a^{2} +b^{2} =c^{2}[/tex]):
Steps
-Plug a, b, and c into the formula [tex]a^{2} +b^{2} =c^{2}[/tex]:
[tex](9)^{2} +(12)^{2} =(15)^{2}[/tex]
-Simplify to get:
[tex]81+144=225[/tex]
-Add:
[tex]225=225[/tex] This is very true. So our answer is correct.
ANSWER: [tex]a=9[/tex]
Sorry for the long explanation, but I hope you understand and that this helps with your question! :)
Answer:
a = 9Step-by-step explanation:
lets make is short and simple
Pythagorean theorem: a² + b² = c²
a² + 12² = 15²
a² = 15² - 12²
a = √81
a = 9
Identify the two factors that were multiplied together to form the array of tiles. Then identify the product of the two factors. Use the variable x in your expressions.
Answers
Answer:
[tex]Terms: 3\ and\ x + 2[/tex]
[tex]Product = 3x + 6[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, there are 3 columns and 3 rows
The 3 columns represent the first factor
To get the second factor, we have to analyze the 3 rows in the attachment.
Notice that the first row is bigger than the other two rows.
This big row will be represented with variable x
Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.
This is represented with + 1
Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.
This is also represented with + 1
Hence, the expression for the rows is x + 1 + 1 = x + 2
The product is then calculated as:
[tex]Product = 3 * (x + 2)[/tex]
[tex]Product = 3 * x + 3*2[/tex]
[tex]Product = 3x + 6[/tex]

Point P is the center of the circle in the figure above. What is the value of x?
Answers
Answer:
x = 80°
Step-by-step explanation:
To find x, we need to create an equation.
Recall that the sum of all the 4 interior angles of a quadrilateral = 360°.
Therefore:
m<B + m<A + m<C + m<P = 360°
m<B = 20° (given)
m<C = 20° (given)
m<A = ½*x = x/2 (inscribed angle theorem)
m<P = (360 - x)°
Plug in the values and solve for x
[tex] 20 + \frac{x}{2} + 20 + (360 - x) = 360 [/tex]
[tex] 20 + \frac{x}{2} + 20 + 360 - x = 360 [/tex]
Collect like terms
[tex] 20 + 20 + 360 + \frac{x}{2} - x = 360 [/tex]
[tex] 400 + \frac{x}{2} - x = 360 [/tex]
Subtract 400 from each side
[tex] 400 + \frac{x}{2} - x - 400 = 360 - 400 [/tex]
[tex] \frac{x}{2} - x = -40 [/tex]
[tex] \frac{x - 2x}{2} = -40 [/tex]
[tex] \frac{-x}{2} = -40 [/tex]
Multiply both sides by 2
[tex] \frac{-x}{2} \times 2 = -40 \times 2 [/tex]
[tex] -x = -80 [/tex]
Divide both sides by -1
[tex] \frac{-x}{-1} = \frac{-80}{-1} [/tex]
[tex] x = 80 [/tex]
