Create an equivalent expression by simplifying the expression below.

BabaBlast [244]

Answer:

see explanation

Step-by-step explanation:

Given

- $\frac{1}{2}$ [ - $\frac{3}{2}$ c + 6c + 1 ] - 3c

Distribute the square bracket by - $\frac{1}{2}$

= $\frac{3}{4}$ c - 3c - $\frac{1}{2}$ - 3c ← combine like terms

= $\frac{3}{4}$ c - 6c - $\frac{1}{2}$

= $\frac{3}{4}$ c - $\frac{24}{4}$ c - $\frac{1}{2}$

= - $\frac{21}{4}$ c - $\frac{1}{2}$

What is the length, in meters, of the ramp, line segment AC, below? Round to the nearest whole number if necessary.

Brrunno [24]

10 meters.

Step-by-step explanation:

To find the missing side of a right triangle, we can use the Pythagorean theorem.

The Pythagorean theorem is...

$a^2+b^2=c^2$

Please be sure to note that a and b will always be the length of the sides and c will always be the hypotenuse, or in this case the ramp.

Since we know the values of both of the sides we can plug this into the theorem.

$6^2+8^2=c^2$

Now we can solve.

$36+64+c^2$

Add.

$100=c^2$

Many people will make the mistake of thinking 100 is the final answer, but since c is squared we need to find the square root of 100.

$\sqrt{100} =10$

c = 10

The ramp is 10 meters.
