Answer:

Step-by-step explanation:

Charla uses 2 cups of mix per 6 cups of water.

2/6 = 1/3

Rae uses 3 cups of mix per 7 cups of water.

3/7

To compare these fractions, we need to find the common denominator. In this case, it's 21.

1/3 = 7/21

3/7 = 9/21

9/21 is greater than 7/21, so Rae's lemonade will taste stronger.

Find the distance between points (1, 2) and (5, 9). Show all work.

vekshin1

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\ \mathsf{d=\sqrt{(5-1)^2+(9-2)^2}}\\\\ \mathsf{d=\sqrt{(4)^2+(7)^2}}\\\\ \mathsf{d=\sqrt{16+49}}\\\\ \mathsf{d=\sqrt{65}}\\\\ \mathsf{d=8.06225774829854...}\\\\ \underline{\mathsf{d\approxeq8.06}}$

The answer is 8.06 uc.

The formula for the perimeter of a rectangle is P=2(l+w). Solve for l.

Readme [11.4K]

Answer:

l = $\frac{P-2w}{2}$

Step-by-step explanation:

Given

P = 2(l + w) ← distribute right side

P = 2l + 2w ( subtract 2w from both sides )

P - 2w = 2l ( isolate l by dividing both sides by 2 )

$\frac{P-2w}{2}$ = l

If 3 pistachio and 1 walnut weigh the same as 10 peanuts, and 1 pistachio and 6 peanuts weigh the same as 1 walnut, how many pea

yuradex [85]

Answer:

Step-by-step explanation:

We need to translate all these statements to equations.

First of all, let P be the pistachios, W the walnuts and N the peanuts.

The first statement "3 pistachio and 1 walnut weigh the same as 10 peanuts" can be represented as:

3 P + 1 W = 10 N

The second statement "1 pistachio and 6 peanuts weigh the same as 1 walnut" can be represented as:

1 P + 6 N = 1 W

If we notice, both equations have a similar term: 1 W. The second gives us the equivalence to the weight of 1 walnut, whereas in the first we have the weight of 1 walnut as an unknown variable. Lets replace it!

3 P + 1 W = 10 P

3 P + (1 P + 6 N) = 10 P

4 P + 6 N = 10 P

We now need to sum (-4P) in both sides to eliminate the 4 P on the left:

4 P + 6 N - 4P = 10 P - 4 P

6 N = 6 P

Dividing both sides by 6:

N = P

Now we need an equation that relates walnuts to peanuts. Lets replace N=P on our firts equation:

3 P + 1 W = 10 P

3 N + 1 W = 10 N

Summing (-3 N) in both sides:

3 N + 1 W - 3N = 10 N - 3N

1 W = 7 N

So, 1 walnut weights the same that 7 peanuts
