4(y - 4)=8
a.-2
b.2
c.4
d.6
Wouldn't it be d.?
5(x - 10) + x
a.6x + 15
b.5x + 15
c.6x + 50
d.4x - 50
Wouldn't it be c.?
9a - b - 2a - 10b
a.-7a + 11b
b.11a + 9b
c.-11a - 9b
d.7a - 11b
Wouldn't it be d.?
#1 yes
#3 yes
#2 hmmm
either 5(x-10)+x = 6x-50
or 5(x+10)+x = 6x+50
Okay thank you! (Sorry it's a day late, I had figured it out on my own after this :-D)
Let's solve each problem step-by-step:
1. 4(y - 4) = 8
First, distribute the 4 to both terms inside the parentheses:
4y - 16 = 8
Next, add 16 to both sides of the equation to isolate the variable term:
4y = 24
Finally, divide both sides of the equation by 4 to solve for y:
y = 6
Therefore, the correct answer is d. 6.
2. 5(x - 10) + x
First, distribute the 5 to both terms inside the parentheses:
5x - 50 + x
Combine like terms:
6x - 50
Therefore, the correct answer is not c. 6x + 50, but rather d. 4x - 50.
3. 9a - b - 2a - 10b
Combine like terms:
(9a - 2a) - (b + 10b)
Simplify further:
7a - 11b
Therefore, the correct answer is d. 7a - 11b.
Let's solve each equation step by step to find the correct answer.
For the first equation:
4(y - 4) = 8
We can start by using the distributive property to remove the parentheses:
4y - 16 = 8
Next, we can isolate the variable y by moving the constant term (-16) to the other side of the equation:
4y = 8 + 16
4y = 24
Finally, we can solve for y by dividing both sides of the equation by 4:
y = 24/4
y = 6
Therefore, the answer is d. 6.
Moving on to the second equation:
5(x - 10) + x
Again, we'll apply the distributive property:
5x - 50 + x
Combining like terms, we have:
6x - 50
Therefore, the answer is d. 4x - 50.
Now, let's solve the third equation:
9a - b - 2a - 10b
We'll group the like terms together:
(9a - 2a) + (-b - 10b)
7a - 11b
The final result is:
7a - 11b
Therefore, the answer is d. 7a - 11b.
So, to recap:
1. The answer to the first equation is d. 6.
2. The answer to the second equation is d. 4x - 50.
3. The answer to the third equation is d. 7a - 11b.
