Answer:
1. 180
2. x = 31
Step-by-step explanation:
1. the sum of the interior angles of every triangle is always 180
2. using what we know from problem 1, we can create an equation:
x + 10 + 2x - 5 + 2x + 20 = 180
add like terms: 5x + 25 = 180
subtract 25 from both sides: 5x = 155
divide both sides by 5: x = 31

What is the slope of y = -1/3x + 2? *
Answer:
-1/3
Step-by-step explanation:
The slope an equation is the number that is being multiplied by x. This is known as the coefficient. A coefficient is a number that’s being multiplied by a variable. In this equation, -1/3 is the slope because that’s the coefficient, it’s being multiplied by the variable x.

Assume y≠60 which expression is equivalent to (7sqrtx2)/(5sqrty3)
Answer:
The equivalent will be:
[tex]\frac{\sqrt[7]{x^2}}{\sqrt[5]{y^3}}=\left(\:x^{\frac{2}{7}}\right)\left(y^{-\frac{3}{5}}\right)[/tex]
Therefore, option 'a' is true.
Step-by-step explanation:
Given the expression
[tex]\frac{\sqrt[7]{x^2}}{\sqrt[5]{y^3}}[/tex]
Let us solve the expression step by step to get the equivalent
[tex]\frac{\sqrt[7]{x^2}}{\sqrt[5]{y^3}}[/tex]
as
[tex]\sqrt[7]{x^2}=\left(x^2\right)^{\frac{1}{7}}[/tex] ∵ [tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a}=a^{\frac{1}{n}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]
[tex]=x^{2\cdot \frac{1}{7}}[/tex]
[tex]=x^{\frac{2}{7}}[/tex]
also
[tex]\sqrt[5]{y^3}=\left(y^3\right)^{\frac{1}{5}}[/tex] ∵ [tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a}=a^{\frac{1}{n}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]
[tex]=y^{3\cdot \frac{1}{5}}[/tex]
[tex]=y^{\frac{3}{5}}[/tex]
so the expression becomes
[tex]\frac{x^{\frac{2}{7}}}{y^{\frac{3}{5}}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\left(\:x^{\frac{2}{7}}\right)\left(y^{-\frac{3}{5}}\right)[/tex] ∵ [tex]\:\frac{1}{y^{\frac{3}{5}}}=y^{-\frac{3}{5}}[/tex]
Thus, the equivalent will be:
[tex]\frac{\sqrt[7]{x^2}}{\sqrt[5]{y^3}}=\left(\:x^{\frac{2}{7}}\right)\left(y^{-\frac{3}{5}}\right)[/tex]
Therefore, option 'a' is true.
The sum of the first two and the greatest of 4 consecutive odd integers is 29. What are the integers?
Answer:
The four consecutive odd numbers are [tex]7,9,11,13[/tex]
Step-by-step explanation:
Let the four consecutive odd integers be [tex]x,x+2,x+4,x+6[/tex]
The sum of the first two and the greatest of 4 consecutive odd integers is 29.
[tex]x+x+2+x+6=29\\3x+8=29\\3x=29-8\\3x=21\\x=7[/tex]
Therefore,
[tex]x=7\\x+2=7+2=9\\x+4=7+4=11\\x+6=7+6=13[/tex]
The four consecutive odd numbers are [tex]7,9,11,13[/tex]

consider the two similar figure below. Which sequence of transformations will carry quadrilateral ABCD onto quadrilateral EFGH
Answer:
The first answer
Step-by-step explanation:
When you dilate something by a fraction the quadrilateral is going to get smaller. So, we can eliminate 2 and 4. Next I took point A and dilated it by 1/2 and then applied the translation to it. Once I figured out where each one landed, the first one was correct because it was on point E of EFGH and the other translation was not.

Answer:
Let x be the number,
7-10x>37
The required inequality is 10x - 7 > 37
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Thirty-seven is less than the difference of seven and ten times a number.
Let x be the number, we get,
10x - 7 > 37
Hence, The required inequality is 10x - 7 > 37

( 30 points ) last one lol pleasee ?
Answer:
H
Step-by-step explanation:
Answer:
The answer is G because:
the y-intercept is -3 because that's what y is when x is 0
the slope is 2 because the y-values are going up by 6 every time and the x values are going up by 3. slope is rise/run (rise is y because it's axis is vertical and the run is x because it's axis is horizontal) so the slope is 6/3 or simplified to 2.
to write the equation you plug in the values above into the slope intercept form which is:
y = mx + b
where m is the slope and b is the y-intercept
so the answer is y= 2x -3 or G

6. Triangle CDE with vertices C(-2,-2), D(1,-4), and E(-3,-4):
a) dilation with scale factor of 4 centered (-1.-3)
b) reflection in the line y = -x
The coordinates of C'D'E' after dilation with the scale factor are; C'(3, 1), D'(-9, -7), E'(7, -7)
How to work with transformation of objects?
We are given the vertices of Triangle CDE as;
C(-2,-2), D(1,-4), and E(-3,-4).
Now when we dilate an object by a scale factor of 4, it means we multiply each coordinate by 4 if it is about the origin.
However, we are told that it is centered about the point (-1.-3).
Thus;
Point C is 1 unit vertically above point (-1.-3) and as such C' will be (1 * 4) = 4 units above the center point.
Point C is 1 unit horizontally to the right of point (-1.-3) and as such C' will be (1 * 4) = 4 units to the right of the center point. Thus, C' is (3, 1)
Point D is 1 unit vertically below point (-1.-3) and as such D' will be (1 * 4) = 4 units below the center point.
Point D is 2 unit horizontally to the left of point (-1.-3) and as such D' will be (2 * 4) = 8 units to the right of the center point. Thus, C' is (-9, -7)
Point E is 1 unit vertically below point (-1.-3) and as such D' will be (1 * 4) = 4 units below the center point.
Point D is 2 unit horizontally to the right of point (-1.-3) and as such D' will be (2 * 4) = 8 units to the right of the center point. Thus, C' is (7, -7)
B) Reflection in the line y = -x gives;
C'(2, -2), D(-1, 4), and E(3, 4)

A drink recipe calls for prune juice and carrot juice. This equation represents the proportional relationship between the number of quarts of prune juice (p) and carrot juice (c) in the recipe. 4p = 12c. Enter the number of quarts of carrot juice used for 1 quart of prune juice.
Answer:
The number of quarts of carrot juice used is approximately 0.3333.
Step-by-step explanation:
The proportional relationship between the quarts of prune juice (p) and carrot juice (c) in the recipe is given as;
4p = 12c
Thus for 1 quart of prune juice, the quarts of carrot juice required can be determined by;
i.e p = 1
So that,
4 x 1 = 12c
4 = 12c
c = [tex]\frac{4}{12}[/tex]
= [tex]\frac{1}{3}[/tex]
= 0.3333
The number of quarts of carrot juice used is approximately 0.3333.
