Can u please help me with these two questions .

scoundrel [369]

Question 1
2x + 4 + x - 7 = 3(x-7)
Add like terms, x-terms add
3x + 4 - 7 = 3(x-7)
Subtract 7 from 4
3x - 3 = 3(x-7)
Multiply out right side with distributive property, 3 times x, and 3 times -7
3x -3 = 3x - 21
Add 21 on each side to cancel -21 on right
3x + 18 = 3x
This is impossible, 3x + 18 cannot equal 3x, plug value in to check, 3(1) + 18 = 3(1), 21 not equal to 3
Question 1 Answer : No Answer

Question 2
4(m-2) = -3(m-16)
Multiply using distributive property on each side
4m - 8 = -3m + 48
Add 8 on each side to cancel -8 on left
4m = -3m + 56
Add 3m on each side to cancel -3m on right
7m = 56
Divide 7 on each side to make 7m : m
m = 56/7
m = 8
Answer to Question 2 : 8

In Asch’s studies, what was the relationship between group size and conformity?

hammer [34]

Answer:

c.Conformity increased rapidly as group size went up, but then leveled off at about 7 people.

Step-by-step explanation:

The conformity increased steadily as the group size went up, but then leveled off at about seven people.

Asch's studies 1956 depicted that group size impact whether subjects conformed or not. The study has revealed that bigger the size of group, more the number of people conformed. But again it was limited to a certain point. Increasing the size of majority beyond three, it was found out that it did not increase the levels of conformity.

Mrs.Cleaver mixes 1.24 liters of red paint with 3 times of blue paint to obtain purple paint. She divides the paint equally in 5

slamgirl [31]

The amount of blue paint in each container is $\fbox{\begin\\\ 0.744 liters \end{minispace}}$ .

Further explanation:

Mrs. Cleaver mixes 1.24 litres of red paint with 3 times blue paint to obtain purple paint.

So, the amount of blue paint used is calculated as,

${3} \times {1.24}=3.72 \text { liters}$

Therefore, the total paint mixture is the sum of blue paint and red paint.

$\fbox{\begin \\\begin{aligned} \text{Total paint}= 1.24+3.72\\=4.96 \text{ liters}\\\end{aligned}\\\end{minispace}}$

Now, as Mrs. Cleaver divides the paint mixture equally in 5 containers so the amount of paint in one container is calculated as,

$\boxed{\begin{aligned}\text{Amount of paint in one container}&= \dfrac{4.96}{5}\\ &=0.992 \text{ liters} \end {aligned}}$

Since amount of blue paint mixed is three times the red paint so the fraction of blue paint to the total paint is $\dfrac{3}{4}$ .

Now, as it is known that the fraction of blue paint to the total paint is $\dfrac{3}{4}$ and the amount of paint in a container is $0.992 \text{ liters}$ then the blue paint in one container is calculated as,

$\boxed{\begin{aligned}\text{Blue paint in one container} =\dfrac{3}{4} \times 0.992\\=0.248 \text{ liters}\end{aligned}}$

Thus, the amount of blue paint in each container is $\fbox{\begin\\\ 0.744 liters \end{minispace}}$ .
