Geo: Worth 50 points and I will give brainliest to right answer! #24

Sindrei [870]

1. ∠1 ≅ ∠3 1. given

∠1 and ∠6 are supplementary angles

∠3, ∠4, and ∠5 are supplementary angles

2. m∠1 = m∠3 2. definition of congruency

3. m∠1 + m∠6 = 180° 3. definition of supplementary angles

m∠3 + m∠4 + m∠5 = 180°

4. m∠3 + m∠4 + m∠5 = m∠1 + m∠6 4. transitive property

5. m∠3 + m∠4 + m∠5 = m∠3 + m∠6 5. substitution property

6. m∠4 + m∠5 = m∠6 6. subtraction property of equality

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l

BigorU [14]

X = the number of humans and y = the number of horses.

x+y=74
2x+4y=196

Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.

$-2(x+y=74)\\2x+4y=196\\\\-2x-2y=-148\\2x+4y=196\\\\2y=48\\y=24$

So, now that you have y, you can plug it into the first equation to find x:

$x+y=74\\x+24=74\\x=50$

So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.

kathy uses a 1/2 cup of milk with every bowl of her favorite cereal if there are only 3 3/5 cups of milk left, then how many bow

Murrr4er [49]

Taking a quotient, we will see that she can make 7 bowls of cereal (and some leftover milk).

<h3>How many bowls of cereal would kathy have?</h3>

We know that for each bowl, she needs 1/2 cups of milk.

And we also know that she has a total of (3 + 3/5) cups of milk.

To know how many bowls she can make, we need to take the quotient between the total that she has and the amount that she needs for each bowl:

(3 + 3/5)/(1/2)

We can rewrite the total as:

3 + 3/5 = 15/5 + 3/5 = 18/5

Then the quotient becomes:

(18/5)/(1/2) = (18/5)*2 = 36/5 = 35/5 + 1/5 = 7 + 1/5

So she can make 7 bowls of cereal (and some leftover milk).
