Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
Answer:
B
Step-by-step explanation:
Hey There!
So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake
2(3x+6)=3(x-10)
step 1 distribute the 2 to whats inside of the parenthesis (3x+6)
2*3x=6x
2*6=12
now we have
6x+12=3(x-10)
step 2 distribute 3 to what's inside of the parenthesis
3*x=3x
3*-10=-30
we're left with
6x+12=3x-30
step 3 add 30 to each side
12+30=42
now we have
6x+42=3x
step 4 subtract 6x from each side
3x-6x=-3x
now we have
-3x=42
step 5 divide each side by -3
42/-3=-14
so x = -14
now lets compare our steps to maya's
as we look at the steps we notice that she messes up on step 2
when distributing 3 to -10
she gets positive 30 but its supposed to be -30
so we can conclude that she mad a mistake from step 1 to step 2
therefore the second one is your answer
How do you find the scale factor of each pair of similar triangles?
The scale factor of triangle M to N is 4/3
How to determine the scale factor?In the above similar triangles, the corresponding sides are:
M = 27 ft
N = 36 ft
So, the scale factor of M to N is:
Scale factor = N/M
This gives
Scale factor = 36/27
Evaluate
Scale factor = 4/3
Hence, the scale factor of triangle M to N is 4/3

Firstly Substitute y=2x-5 into 5x-4y=-10
This will be 5x-4(2x-5)=10 now solve for x
5x-8x+20=-10
-3x=-30
X=10
Now sub x as 10 into the second equation y=2x-5

Answer:
[tex] \purple {\bold {m\angle PTR=136\degree}} [/tex]

Step-by-step explanation:
PS and RS are tangents to the circle with center T at points P and R. (given)
TP and TR are radii of the given circle.
[tex] \therefore PS\perp TP\: \&\: RS\perp TR[/tex]
(radius is perpendicular to the tangent)
[tex] \therefore m\angle TPQ= m\angle TRS =90\degree [/tex]
In quadrilateral SPTR
[tex] m\angle TPQ+ m\angle TRS+m\angle PSR +m\angle PTR=360\degree [/tex]
[tex] 90\degree+ 90\degree+44\degree +m\angle PTR=360\degree [/tex]
[tex] 224\degree +m\angle PTR=360\degree [/tex]
[tex] m\angle PTR=360\degree - 224\degree[/tex]

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units
Answer:
the answer is: 8(x)= 4 -5
Step-by-step explanation:
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.
The given function is g(x)=x-5.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here, parent function is g(x) = x
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted down: 5 units
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

Area of Pentagon = (5/2) x s x a
So,
= 5/2 x 4 x 2.75
= 5 x 2 x 2.75
= 10 x 2.75
= 27.5 cm²
= 28 cm²
Thus,
