Work algebraically and you must show equation used and the work used to get your answers.

Well, it is $\frac{-2}{25}$ . That is, the equation is $y=\frac{-2}{25}x+30$ . The run could be found when y=0, so $\frac{-2}{25}+30=0$ or $30=\frac{2}{25}x$ or $750=2x$ or $x=375$ . 375 inches. 30 feet means 360 inches, as far as I remember (in my country only metric systems are being used :) ) so it doesn't really work -- the ramp is just a bit too long.

Find the measure of ∠C. A) 10° B) 14° C) 20° D) 30°

rosijanka [135]

The answer is C) 20°. This is because 73 + 87 = 160, and there are 180° in a triangle so 180 - 160 = 20. I hope this helps!

which property is illustrated by the following statement? 2(-3/9)=(-3/9)2^? Associative Property of Addition, Commutative Proper

Ratling [72]

Consider the given statement:

$2(\frac{-3}{9}) = (\frac{-3}{9})2$

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that $a \times b = b \times a$ .

In the given statement, $2(\frac{-3}{9}) = (\frac{-3}{9})2$

This statement holds commutative property of multiplication as whether 2 is multiplied to $\frac{-3}{9}$ or $\frac{-3}{9}$ is multiplied to 2, the result is same.

So, Commutative property of multiplication is illustrated in this statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ . This property is not used in the given statement.

crimeas [40]

Answer:

x= (4z-4)/3

Step-by-step explanation:

3z+8=12+3x-z

3z + z +8 -12 = 3x

4z - 4 =3x

x= (4z-4) / 3

Someone please help me with the problem. it’s due tomorrow and idk what i’m doing

Hatshy [7]

For the first question:Using the distance=rate x time formula (d=rt). Your equation would be y=38x. The 38 comes from the kathryn’s speed(rate).

For the second question: because you know the distance is now 53 substitute 53 for y and solve. 53=38x. Where x represents her time. She travels the 53 miles at a rate of 38mi/h (53 divided by 38) and solve in terms of hours 1.3947or rounded to the nearest tenth 1.4 which in terms of hours is 1 hour 24 minutes.
