\bf \stackrel{\textit{initial length of the snake at 0 months, a = 0}}{L=\cfrac{7}{4}(0+5)\implies L=\cfrac{35}{4}\implies L=8.75}
\\\\\\
\stackrel{\textit{length of the snake at 5 months, a = 5}}{L=\cfrac{7}{4}(5+5)\implies L=\cfrac{70}{4}\implies L=17.5}

since the snake is 8.75 inches originally, over the next 5 months it grew to 17.5, so the difference of 17.5 - 8.75 = 8.75, meaning the snake really grew only 8.75 inches over the 5 months, from its original 8.75 inches in length.

It's asking how long does a garden snake grow over 5 months instead of the length of the five-month-old garden snake. So the calculation is L=7/4*5=8.75. If it's hard to understand, try subtract the length of the snake when it's 1 month old from the length of the snake when it's 6 months old. You'll get the same answer.

A circle has been split into 8 sectors each of which can be colored as 4 different colors, and no consecutive sectors are colore
Eva8 [605]

Answer:

5832 ways

Step-by-step explanation:

Since the circle has 8 sectors and there is 4 colour,

Assuming the sectors are numbered 1 to 8,

Sector 1 : can be coloured with any of the 4 colour in 4 ways

Sector 2 can be coloured with any of the remaining 3 colours in 3 ways

Sector 3 in 3 ways without using the colour in sector 2

Sector 4 in 3 ways without using the colour in sector 3

Sector 5 in 3 ways without using the colour in sector 4

Sector 6 in 3 ways without using the colour in sector 5

Sector 7 in 3 ways without using the colour in sector 6

Sector 8 in 2 ways without using the colours in sector 1 and 7

Number of ways of colouring = 4*3*3*3*3*3*3*2 = 5832 ways

The measure of an angle is 8 times the measure of its complement. tina writes an equation and finds the correct measure of each
pogonyaev
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)

With all this information, you should have the equation:

n + 8n = 90

To solve, combine like terms to get:

9n = 90

Divide by 9 on both sides to isolate the variable n.

n = 10

Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.

mihalych1998 [28]

Answer:

The expression –3 + 2x is equivalent to 2x – 3. I know it is equivalent because for every value of x that is substituted in, the two expressions simplify to the same value. I took the expression and used the commutative property to not change the value.
