Answer:
The slope is -3
Step-by-step explanation:
Find 2 points (-2,3) (-1,0) are 2.
Next subtract y 1 by y 2 in this example, 3-0 which equals 3
After that, subtract x 1 and x 2. In this example, -2-(-1) which equals -1.
Now dive y over x. 3/-1 or -3.
So the slope is -3.
Answer:
![1 \frac{5}{8}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B5%7D%7B8%7D)
Step-by-step explanation:
To figure out this problem we need to divide 6 1/2 by 4.
Convert any mixed numbers to fractions. Then your initial equation becomes:
![\frac{13}{2} \div \frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%20%5Cdiv%20%5Cfrac%7B4%7D%7B1%7D)
Applying the fractions formula for division:
![= \frac{13 \times 1}{2 \times 4}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B13%20%5Ctimes%201%7D%7B2%20%5Ctimes%204%7D)
![= \frac{13}{8}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B13%7D%7B8%7D)
Simplifying 13/8, the answer is:
![= 1 \frac{5}{8}](https://tex.z-dn.net/?f=%3D%201%20%5Cfrac%7B5%7D%7B8%7D)
8(1.65)R + 98.70 = 242.58 13.20R = 143.88 [subtract 98.70 from both sides] R = $10.90 / hr. [divide both sides by 13.20]
Answer:
<em>Square= 12 units</em>
<em>Triangle long sides= 19 units</em>
<em>Triamgle short side= 10 units</em>
Step-by-step explanation:
<em>It is a square, so all sides are the same. That means 3x+3 equals 4x. What number can be subsituted into x to equal 4? If x is 3, then 3x+3 would be 3(3)+3. It equals 12. 4 times 3 is also 12. It works! That also means the square's side is 12 units.</em>
<em>Square= 12 units</em>
<em />
<u><em>So, x=3</em></u>
<em />
<em>The triangle's longer sides are 7x-2. Subsitute x in, which is 3, and you get 7(3)-2. It equals 19. The two longer sides of the triangle are the same length, so both are 19 units.</em>
<em>Triangle long sides= 19 units</em>
<em />
<em>The triangles shorter side is 2x+4. Subsitute 3 in for x and you get 2(3)+4. It equals 10, so the shorter side is 10 units.</em>
<em>Triangle short side= 10 units</em>
