Answer:
9/10 or 0.9
Step-by-step explanation:
X equals the smallest. x+2 equals the next largest and x+4 equals the third largest.
x+(x+2)= 3(x+4)
2x+2= 3x+12
2x= 3x+10
-x=10
x=-10
Final answer: -10, -8, -6

Step-by-step explanation:
<u>Step 1: Define</u>
-29 = 9 - 6k - 2k - 1
<u>Step 2: Solve for </u><em><u>k</u></em>
- Combine like terms: -29 = 8 - 8k
- [Subtraction Property of Equality] Subtract 8 on both sides: -37 = -8k
- [Division Property of Equality] Divide -8 on both sides: 37/8 = k
- Rewrite/Rearrange: k = 37/8
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: -29 = 9 - 6(37/8) - 2(37/8) - 1
- Multiply: -29 = 9 - 111/4 - 37/4 - 1
- Subtract: -29 = -75/4 - 37/4 - 1
- Subtract: -29 = -28 - 1
- Subtract: -29 = -29
Here we see that -29 does indeed equal -29.
∴ k = 37/8 is the solution to the equation.
Answer:
33
Step-by-step explanation:
f(4) = 4(4) - 3 = 16 - 3 = 13
g(-5) = -2(-5) + 10 = 10 + 10 = 20
13 + 20 = 33
Answer: 151
Step-by-step explanation:
12 x 13 = 156
156 - 5 = 151
