Answer:
c = -4
Step-by-step explanation:
Step 1: Write equation
14 = -2c - 6 - 3c
Step 2: Solve for <em>c</em>
- Combine like terms: 14 = -5c - 6
- Add 6 on both sides: 20 = -5c
- Divide both sides by -5: c = -4
Step 3: Check
<em>Plug in c to verify it's a solution.</em>
14 = -2(-4) - 6 - 3(-4)
14 = 8 - 6 + 12
14 = 2 + 12
14 = 14
It will take them 20 hours, since the question is asking how long it will take them when working together you add each of their hours together,9+11=20
Answer:
15 unit
Step-by-step explanation:
Applying
/RT/ = √[(y₂-y₁)²+(x₂-x₁)²]............. Equation 1
Where /RT/ = distance between point R and Point T
From the question,
Given: y₁ = -9, x₁ = 8, y₂ = -9, x₂ = -7
Substitute these values into equation 1
/RT/ = √[(-9-(-9))²+(-7-8)²]
/RT/ = √[(0)²+(-15)²]
/RT/ = √225
/RT/ = 15 unit
Hence the distance between point R and point T is 15 unit
Answer:
33.334 percent chance, or a 1 in 3 chance.
Step-by-step explanation:
divide 100 percent by the 9 places, there are 3 options for each, so multiply that to be 1 in 3 bam. Also the decimal isnt exactly precise, i rounded at some point to make it easy.
