Answer:

B $(y-9)=5(x-1)$

Step-by-step explanation:

Formula of straight line in Point slope form

$(y-y_1)=m(x-x_1)$

Here

$m=5 \ and \ (x_1, y_1)=(1, 9)$

therefore equation of line having slope 5 and passing through point )1, 9) is given as

$(y-9)=5(x-1)$

There are 52 birds and acts in the store. For the same animals Kia counts 138 legs. How many birds and cats are in the pet store

KiRa [710]

Let's represent birds by the letter x and cats by the letter y. Since birds have 2 legs, and cats have 4, we can express this as:
$138 = 2x + 4y$
$52 = x+y$

We can solve by substitution. Let's solve for x in the second equation:
$x = 52-y$

Replace every x in the first equation by that:
$138 = 2(52-y)+4y$
$138 = 104-2y+4y$
$138 = 104 + 2y$
$34 = 2y$
$y = 17$

Now, plug that in for y in second equation and solve for x:
$52 = x + 17$
$x = 35$

Since x was the number of birds and y was the number of cats in the store, there are 35 birds and 17 cats in the store.

Answer:

The formula to find the value of the side is X ^ 3 = 10, and the side measures 2.15 cm.

Step-by-step explanation:

Given that a Rubik's Cube has a volume of 10 cm, to write an equation to find the length of the sides and find the length of the side to the nearest tenth, the following calculations must be performed, knowing that the volume of a cube is obtained to enhance one of its sides to the third:

X ^ 3 = 10

X = 3√ 10

X = 2.15

Thus, the formula to find the value of the side is X ^ 3 = 10, and the side measures 2.15 cm.

Lisa and Ann are eating a box of crackers. Lisa eats 3/6 of the box,and Ann eats 1/4 of the box.How much of the box did the two

Rufina [12.5K]

<h2>Lisa and Ann ate 3/4 of the box together</h2>

<em><u>Solution:</u></em>

Given that,

Lisa and Ann are eating a box of crackers

$Lisa\ ate = \frac{3}{6}\\\\Ann\ ate = \frac{1}{4}$

<h3><u>How much of the box did the two girls eat together?</u></h3>

$Together\ eaten = Lisa\ ate + Ann\ ate\\\\Together\ eaten = \frac{3}{6} + \frac{1}{4}\\\\Together\ eaten = \frac{1}{2} + \frac{1}{4}\\\\Together\ eaten = \frac{1 \times 2}{2 \times 2} + \frac{1}{4}\\\\Together\ eaten = \frac{2}{4} + \frac{1}{4}\\\\Together\ eaten = \frac{3}{4}$
