Answer:

Step-by-step explanation:

This is an equilateral triangle, the 3 sides are equal.

Also, that means 3 angles are equal.

Given the 2 angles, we can say:

2x - 4 = 5y

Also, the angle is "5y" as they are equal.

Sum of 3 angles of a triangle is 180, so we can write:

2x - 4 + 5y + 5y = 180

2x + 10y - 4 = 180

2x + 10y = 184 [Equation 2]

From the first equation we can solve for y:

$2x - 4 = 5y\\y=\frac{2x-4}{5}$

Now, we plug this into Equation 2 and find x:

$2x+10y=184\\2x+10(\frac{2x-4}{5})=184\\2x+4x-8=184\\6x=192\\x=32$

So x is 32

Answer:

Step-by-step explanation:

Subtraction is not commutative. For example, 4 − 7 does not have the same difference as 7 − 4. The − sign here means subtraction.

However, recall that 4 − 7 can be rewritten as 4 + (−7), since subtracting a number is the same as adding its opposite. Applying the commutative property for addition here, you can say that 4 + (−7) is the same as (−7) + 4. Notice how this expression is very different than 7 – 4.

Professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot. find the recommended slope for a sewe

erik [133]

We have been given that professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot.

Therefore, we can find the slope as:

$\text{Slope}=\frac{0.25\text{ inch}}{\text{1 foot}}=\frac{0.25\text{ inch}}{\text{12 inch}}$

$\text{Slope}=\frac{0.25}{12}=\frac{25}{1200}=\frac{1}{48}$

Therefore, the recommended slope for a sewer pipe is $\frac{1}{48}$

Which graph represents the inequality y>3−x?

nekit [7.7K]

Answer:

Step-by-step explanation:

The first step is to draw the line y = 3 - x to see what the line itself looks like. Is it going from left to right as in A and C is going up as you go from right to left as in B and D? The graph on the left (below) gives you the answer. It is going up as you progress from right to left.

The next step is to answer which is it: B or D.

y has to be above the line. it is B. See the graph below on the right.
