my first expression answer is y=5 -2x How do I plug it into x-y=1 ?? The Y
1. x-5-2x=1 OR
2. x+5-2x=1
Answer:
All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:
given the second expression:
x - y = 1
We'll replace y with it's value in the first expression:
x - (y) = 1
x - (5 - 2x) = 1
Now we can expand the resulting equation:
x - 5 + 2x = 1
So neither of the answers provided are correct.
You can then solve for x:
x - 5 + 2x = 1
x - 5 + 5 + 2x = 1 + 5
x + 2x = 6
3x = 6
3x/3 = 6/3
x = 2
After that, you can find y by plugging x into either of the two original equations:
y = 5 - 2x
y = 5 - 2(2)
y = 5 - 4
y = 1
PLEASE HELP!! QUICK!! WORTH 80 POINTS!!!
A?
B?
C?
D?
and proof.
Answer:
C
Step-by-step explanation:
Key skills needed: Inequalities
1) We are given that inequality.
The inequality is b ≤ 11 (any variable would work instead of "b")
--> It is "≤" and not "<" since there is a filled/shaded dot on the 11.
2) This means we solve all the ones with less than or equal to symbols.
A does not have a ≤ symbol, so A cannot be it
3) Solve each one:
B --> -k [tex]\leq[/tex] 11
Divide by -1 on both sides and get [tex]k \geq -11[/tex] B cannot be it
C --> 44 ≥ b + 33
Subtract 33 from both sides and get b [tex]\leq[/tex] 11
Therefore C is your answer C can be it!!
If you want to check D --> x -11 ≤ 11
Add 11 to both sides and get x ≤ 22 D cannot be it
Hope you understood and have a nice day!!
Answer:
C. 44 ≥ b+33
Step-by-step explanation:
Lets think about this. It really doesn't matter what the variable is also, we should immediately disregard A because its not a greater than or equal to sign. You should also, you how I can to this conclusion was that, SHADED circle in are always greater than or equal to or less than or equal to. EMPTY circle means greater than or less than. Therefore, you have already taken down A. B on the other hand would've worked if not for the fact that the variable is a negative. D on the other hand if you do the math of what the number line would be 11 -11=0 while it is less than or equal to 11. To get 11 or anything else other than below 0 you would fall off the number line. Therefore, because 44≥b+33 would be 44≥11+33 or anything less would work.
C. 44 ≥ b + 33

How much pure acid is in 860 milliliters of a 18% solution?
The answer is ____ ml.
Answer:
The answer is 154.8 ml
Step-by-step explanation:
In this question, the amount of pure acid is 18% of the total solution, that is, 18% of 860 milliliters. So
0.18*860 = 154.8 ml
The answer is 154.8 ml
Solve for x.
I will give brainliest
Answer:
22.5
Step-by-step explanation:
Everything equals 180. This means that the 90 degree angle creates half of that would mean that everything on the right side of the 90 degree angle, also has to equal 90 degrees. X=22.5 because you have to combine like terms meaning x + 3x = 90- 4x=90. Divide by 4 on both sides of the equals sign. Plug that into a calculator and you get 22.5 Since it is only asking for the singular x, you don't have to solve for 3x. (It would be 67.5)

Answer:
C = 133.33°
Step-by-step explanation:
Apply the Law of Cosines to find angle C:
[tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex]
Where,
a = 8.5 cm
b = 4.1 cm
c = 11.7 cm
Plug in the values
[tex] Cos(C) = \frac{8.5^2 + 4.1^2 - 11.7^2}{2*8.5*4.1} [/tex]
[tex] Cos(C) = \frac{-47.83}{69.7} [/tex]
[tex] Cos(C) = -0.6862 [/tex]
[tex] C = Cos^{-1}(-0.6862) [/tex]
C = 133.33°
6 batteries cost 29 dollars what is the unit rate?
Answer:
Step-by-step explanation:
In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour
Answer:
[tex]\large \boxed{\sf{4.83 \ dollars/battery}}[/tex]
Step-by-step explanation:
Unit rate is a ratio that compares two measurements.
Denominator is 1
[tex]\displaystyle \sf \frac{29\ dollars}{6\ batteries}=4.83\ dollars/battery[/tex]

Step-by-step explanation:
Uncle John has 32 lemon trees and 28 lime trees to plant on his grove. He would like to plant the trees in rows where each row has the same number of lemon trees and each row has the same number of lime trees. What is the greatest number of rows Uncle John can plant?
Answer:
The greatest number of rows is 10.
To find this you can do 32 plus 28 which equals 60 then you know 60 divided by 10 is 6 so you could have six rows and six columns or 10 rows and six columns and 10 is greater than six.
So, the greatest number of rows you can have is 10.

Describe how you can tell whether a lines slope is greater than 1,equal to 1, or less than 1
Answer:
Rise over Run
Step-by-step explanation:
You need to find the rise over run. Find a point where the line crosses a set of points on the graph. Then find another point on the graph where the line crosses. start at the bottom point and count up till you get even to where the point is. then count over till you get to the point. That is your rise over run. Now simplify the rise over run. You should get a number and that is how you can tell if if a lines slope is equal to 1, greater than 1, or less than 1.

In the coordinate plane, the point X (3, -2) is translated to the point X'(2, - 4). Under the same translation, the points Y (7, 1) and Z (-1, 2) are
translated to Y' and Z', respectively. What are the coordinates of Y' and Z'?
Answer:
The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)
Step-by-step explanation:
Translations
A given point A(x,y) when translated by the rule (h,k) maps to A'(x+h,y+k).
We are given the point X(3,-2) and its image at X'(2,-4). The rule for the translation used is:
(h,k)=(2,-4)-(3,-2)=(2-3,-4+2)=(-1,-2)
If we apply the same translation to the point Y(7,1) we get the image Y'(7-1,1-2)=Y'(6,-1).
If we apply the same translation to the point Z(-1,2) we get the image Z'(-1-1,2-2)=Z'(-2,0).
The coordinates of Y' and Z' are, respectively Y'(6,-1) Z'(-2,0)
