Answer:
Step-by-step explanation:
[3x-2]÷4=2x-8
3x-2 = 4·(2x-8)
3x-2 = 8x-32
-2 = 5x-32
30 = 5x
x = 6
Answer:
(3x-2)/4= 2x-8 x=6
Step-by-step explanation:
(3x-2)/4 times 4= 2x-8
Multiply both sides by 4
3x-2/4 times 4= 2x times 4-8 time 4
Simplify
3x= 8x = 8x-30-8x
Subtract 8x from both sides
3x-8x=8x-30-8x
Simplify
-5x=-30
Divide both sides by -5
-5x/-5 = -30/-5
Simplify so you get x=6
Andy's little brother has a toy box that
contains 2 blue race cars, 1 green race car,
and 1 red race car. Andy removes 2 race cars
from the toy box without looking. If Andy
removes a blue car first and does not replace
it, which best represents the sample space
for the cars Andy removes?
Answer:
c.
Step-by-step explanation:
The solution is Option C.
Sample space is set A = { blue , blue } , { blue , green } , { blue , red }
What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the sample space be represented as set A
Now , the equation will be
The number of blue cars = 2 blue cars
The number of green cars = 1 green car
The number of red cars = 1 red car
So , the total number of cars = 2 + 1 + 1 = 4 cars
Now , Andy removes 2 race cars from the toy box without looking
Let the first removed car be a blue car
So , the second car can have any value including a blue , green or white
And , the sample space is given by set A
Set A = { blue , blue } , { blue , green } , { blue , red }
Hence , the set is { blue , blue } , { blue , green } , { blue , red }

Which of the following could be the side lengths of a triangle?
Answer:
D. 12, 15, 25
Step-by-step explanation:
The triangle leg rule states that the smaller two lengths must add up to be greater than the largest length.
This means that the first two values must add up to be greater than the final value.
12 + 15 = 27
27 > 25

Answer:
A) 2481.156[tex]\pi[/tex] cm³
Step-by-step explanation:
The formula for volume of a sphere is: [tex]\frac{4}{3} \pi r^{3}[/tex]. In this case, the radius is 12.3. 12.3 cubed is: 1860.867. 1860.867 x 4 is 7443.468. 7443.468 divided by 3 is 2481.156. Since we haven't multiplied by pi yet, the answer would be 2481.156[tex]\pi[/tex].

Mia used 1/7 of an ounce of nuts to make 1/5 of a cake. How many ounces of nuts are needed to make a whole cake?
Answer:
For this case we can apply the following proportional rule:
Step-by-step explanation:
1/7 nuts. x
------------ = ----------
1/5 cake. cake
and solving for x we got:
x = 1/7
------- = 5/7 nuts
1/5

Timo was curious if quadrilaterals LMNR and PQNO were similar, so he tried to map one figure onto

R
Q
Timo concluded:
"It's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations,
so the quadrilaterals are not similar."
Answer:
c
Step-by-step explanation:
The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.
What is rigid transformation?Rotations, reflections, and translations are known as rigid transformations. They do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.What is dilation?Dilation is not a rigid transformation, since they change the size of a figure. Dilation would not change the shape but changes the sizeThis would give us a similar, but not congruent figure.Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".

how do I simify by combining like terms
Answer: Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.
Step-by-step explanation:
Answer:
If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.
Step-by-step explanation:
For example this equation:
2x + 7b - 7x + 9b + 1a - 22a
So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them
category x(only numbers that have x's go here): +2x-7x = -5x
category b (only numbers that have b's go here): +7b+9b = +16b
category a (only numbers that have a go here): +1s-22b = -21a
now just put them in the same equation:
-5x+16-21a
and done!^^
Hope this example helped~
