Answer 1

Answer: 1. Selena has to walk to school and from school.
That means that each day, she walks the distance from her house to the school twice.
If she walks 2/3 in a day, the distance must be half of that, or 1/3.

2. 3 batches = 3/4 cup.
Divide each side by 3.
1 batch = 1/4 cup.

3. 5 eighths minus 1 eighth = 4 eighths.
Since we have the same bottom number, we don't need to do anything special. This problem is just the same as something like 5 apples - 1 apple.

4. First, let's convert 6 into thirds.
6 × 3 = 18
Therefore, 6 = 18/3.

Add 6 and 2/3.
18/3 + 2/3
20/3

5. To be a composite number, a number needs to be divisible by something besides 1 or itself.
Check your divisibility rules...
39 is divisible by 3 (39 ÷ 3 = 13), so this could be his house number.

6. 12 cupcakes - 9 chocolate = 3 vanilla.
3 vanilla cupcakes out of 12. (3/12)
We can simplify this fraction. 3 and 12 are both divisible by 3.
3/12 = 3÷3 / 12÷3 = 1/4

Answer 2

Answer: number one is 1/3 because 1/2 of 2/3 is 1/3

Y = 4x+1 y=x^2 + 2x - 2 A.6,2 B. 2,6 C. -6,2 D. -6,-2

Answers

Answer:

The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Step-by-step explanation:

Given that

$y = 4x + 1 (i)$

$y = x^2 + 2x -2 (ii)$

Now, by susbstituting the value of 'y' from equation i to equation ii, we get

$4x+1=x^2 + 2x -2$

$0=x^2 + 2x -2-4x-1$

$0=x^2 + (2x -4x) +(-2-1)$

$0=x^2 + (-2x) +(-3)$

$0=x^2 -2x -3$

$x^2 -2x -3 = 0 (iii)$

Now by factorization, equation iii can be written as

$x^2 -3x +x -3 = 0$

$x(x -3) + 1(x -3) = 0$

$(x -3)(x +1) = 0$

x = 3 and x = -1

By putting the values of x in equation i, we get

y = 4(3) + 1

y = 12 +1

y = 13

and

y = 4(-1) + 1

y = -4 +1

y = -3

Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Solve for L: S=2WL+2LH+2WH

Answers

Answer:

Step-by-step explanation:

S = 2WL + 2LH + 2WH

S - 2WH = 2WL + 2LH

S - 2WH = L(2W + 2H)

(S - 2WH) / (2W + 2H) = L <===
