2.5 is your answer because first we divide the numbers then subtract 2 from both sides and simplify
Arturiano [62]2 years ago

Answer:

2.5

Step-by-step explanation:

First divide 4 by 2

Second, you want x on a side by itself. So you would move 2 over to 9.5. But since 2 is positive, you would subtract 2 from 9.5

Third, you need to get x by itself. So you would divide by 3 on both sides because division cancels out multiplication which is what 3x is. And then you end up with 2.5

3x + 4 / 2 = 9.5

3x + 2 = 9.5

3x = 7.5

3x/3 = 905/3

x = 2.5

And if you want to check it, just substitute 2.5 for x

3(2.5) + 4 / 2 = 9.5

7.5 + 4 / 2 = 9.5

7.5 + 2 = 9.5

9.5 = 9.5

Karen has 4h storyboiks. Karen's storybook collection is 2/3 of what Mary's collection is. How many storybooks do they have in a
Dafna11 [192]
In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x

2/3  x     =   4h

x             = 3/2 . 4h

x           =    6h

The storybooks they have in total would be : 6h  + 4h = 10 h

hope this helps

Which equation demonstrates the additive identity property?
Bezzdna [24]

Answer:

Step-by-step explanation:

Solve for o in the equation (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 41o(7 + 4)(1) = 7 + 41o(7 + 41) + ( - 7 - 41) = 0

We first need to simplify the expression removing parentheses

Simplify 41o(7 + 4): Distribute the 41o to each term in (7+4)

41o * 7 = (41 * 7)o = 287o 41o * 4 = (41 * 4)o = 164o

Our Total expanded term is 287o + 164o

Simplify 41o(7 + 41): Distribute the 41o to each term in (7+41)

41o * 7 = (41 * 7)o = 287o 41o * 41 = (41 * 41)o = 1681o

Our Total expanded term is 287o + 1681o

Our updated term to work with is (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 287o + 164o(1) = 7 + 287o + 1681o + ( - 7 - 41) = 0

We first need to simplify the expression removing parentheses

Simplify 164o(1): Distribute the 164o to each term in (1)

164o * 1 = (164 * 1)o = 164o Our Total expanded term is 164o

Our updated term to work with is (7 + 4) + (7 - 41) = 14©(7 + 4) + 0 = 7 + 287o + 164o = 7 + 287o + 1681o + ( - 7 - 41) = 0

Step 1: Group variables: We need to group our variables (7 and 14©(7. To do that, we subtract 14©(7 from both sides (7 - 14©(7 = 14©(7 - 14©(7

Step 2: Cancel 14©(7 on the right side: 0o = 0 Step 3: Divide each side of the equation by 0

0o 0 = 0 0 o =

Use the discriminant to find the number of real roots in Y = x^2 – 6x + 9
BaLLatris [955]
So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0

As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.
