The solution to an equation is the true value of the equation
So, Maria's solution is incorrect
The equation is given as:
[tex]-5n = -9[/tex]
And the solution is given as:
[tex]n = 1[/tex]
To determine if her solution is correct, then she needs to substitute her solution in the given equation.
In other words, substitute 1 for n in [tex]-5n = -9[/tex]
[tex]-5 \times 1 = -9[/tex]
Multiply -5 and 1
[tex]-5 = -9[/tex]
The above equation is false.
This is so, because -5 does not equal -9
i,e, [tex]-5 \ne -9[/tex]
Hence, Maria's solution is incorrect

-4/7v = -8 2/3
Show how you did it please :)
Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12

How many 0.8 liter glasses can be filled by a 6.8 liter pitcher?
Answer:
8.5 glasses
Step-by-step explanation:
6.8L / 0.8L = 8.5 glasses
Answer:
8 glasses
Step-by-step explanation:
You divide [tex]6.8/0.8[/tex]
This gives you 8.5 glasses
since 9 glasses is too much, at 7.2 liters. The maximum glasses possible is 8 assuming you're not filling a half of the glass which would be 8.5 glasses.

Cosx=4/5 what is sin2x cos2x and tan2x
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5

Answer:
350
Step-by-step explanation:
Answer:
C. 350 pounds
Step-by-step explanation:
Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.
In your own words, what is a radical expression?
Answer:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.
