What is the answer to 4(-x + 4) =12
Hey there!
4(-x + 4) = 12
4(-x) + 4(4) = 12
-4x + 16 = 12
SUBTRACT 16 to BOTH SIDES
-4x + 16 - 16 = 12 - 16
CANCEL out: 16 - 16 because it gives you 0
KEEP: 12 - 16 because it helps solve for the x-value
NEW (temporary) EQUATION: -4x = 12 - 16
12 - 16 = -4
NEW EQUATION: -4x = -4
DIVIDE -4 to BOTH SIDES
-4x/-4 = -4/-4
CANCEL out: -4/-4 (the LEFT side) because that gives you 1
KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value
x = -4/-4
x = 1
Therefore, your answer is: x = 1
Good luck on your assignment and enjoy your day!

Decide whether it would be more convenient to solve the system of equations by substitution or elimination.
2 = 4y - 10
7x +12y = 7
The more convenient method to solve the given system of equations is by elimination.
Solving systems of linear equationFrom the question, we are to determine whether it would be more convenient to solve the system of equations by substitution or elimination
The given system of equations is
2 = 4y - 10 ----------- (1)
7x +12y = 7 ----------- (2)
In equation (1), we can see that there is no variable x in the equation. Thus we can solve for y and then substitute the value of y into equation (2).
That is,
From equation (1)
2 = 4y - 10
2 + 10 = 4y
12 = 4y
12/4 = 4y/4
3 = y
∴ y = 3
Now, we can substitute the value of y into equation (2) to determine the value of x
Hence, the more convenient method to solve the given system of equations is by elimination.

How to do q6 (a) and (b)? please help!!!
ignore my draft haha
a)
The sides of small squares are x and y, therefore the side of the big square is x + y.
The shaded region has an area:
(x + y)² - x² - y² = x² + 2xy + y² - x² - y² = 2xyb)
After the dimension changes the new side lengths are:
x - 2 and y + 2Since x and y are integers greater than 1, the minimum value of x is 2 (x = 1 doesn't work as we get negative value of x - 2) and same of y is 3 as y > x.
With this the smallest possible area of the shaded region is:
2xy = 2*2*3 = 12 cm²what is the product of 0.35 and 0.46? (with solution please)

Which table represents a linear function?
Answer:
Table 1 (leftmost)
Step-by-step explanation:
A linear function has a common difference between all of the x-values. This means that all the x-values change by the same amount relative to the change in y. In this case, the x-value increases by 1/2 every time that y increases by 1. The other tables do not work because their change is inconsistent. There is no number being added each time. Therefore, they are not linear. If you were to graph these tables, only table 1 would make a straight line.
A square has side of length y units what is the area?
Super hero academy's ratio of boys to girls is 5:3. If 7th grade has 150,
7th grade students how many boys and girls are in 7th grade?
Answer:
94 boys and 56 girls.
Step-by-step explanation:
150/8 = 18.75 = x
b=x*5 = 94
g=x*3 = 56
b+g=150
Looking at the question, we see that the ratio of boys to girls is 5:3, the total is 8. We are trying to find what the ratio of boys to girls is while the total is 150. Now, we can easily divide 150 by 8, finding one part of our answer! 150 ÷ 8 ≈ 18 [tex]\frac{3}{4}[/tex]. now to multiply that by the amount of boys and girls (5:3), 18 [tex]\frac{3}{4}[/tex] × 5 = 93 [tex]\frac{3}{4}[/tex] and 18 [tex]\frac{3}{4}[/tex] × 3 = 56 [tex]\frac{1}{4}[/tex]. After we round we get 94:56.

A rectangular prism has a height of 12 yards and a base with area of 53 square yards what is its volume
Answer:
16
Step-by-step explanation:
Use the distributive property to remove the parentheses.
-3(-6y +3w-2)
Answer:
18y-9w+6
Step-by-step explanation:
-3*-6y=18y
-3*3w=-9w
-3-2=6
so, 18y-9w+6
Answer:
18y-9w+6
Step-by-step explanation:
The distributive property tells that because the -3 is outside of the parentheses, we multiply all values inside the parentheses by -3.
So, -6y * -3 is 18y because two negatives cancel out, 3w * -3 equals -9w, and -2 * -3 is 6, again because two negatives cancel each other out.
We put this all together, the parentheses and -3 is removed, and the expression becomes 18y-9w+6.

Find the least common multiple of 14 and 28.
Answer:
The LCM of 14 and 28 IS 28
Step-by-step explanation:
Based on a poll
, among adults who regret getting tattoos, 14% say that they were too young when they got their tattoos. Assume that six adults who regret getting
tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below.
a. Find the probability that none of the selected adults say that they were too young to get tattoos
(Round to four decimal places as needed.)
The probability that none of the selected adults say that they were too young to get tattoos is 0.3512
What is Binomial probability distribution?The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
14% say that they were too young when they got their tattoos.
So, p= 0.14.
Six adults who regret getting tattoos are randomly selected
So, n=6.
Now, the probability that none of the selected adults say that they were too young to get tattoos.
P(X=0) = [tex]C_ {6.0} (0.14)^{0} (0.86)^{6}[/tex]
= 0.3512
