Answer:
14 =x
Step-by-step explanation:
We can use ratios to solve
5 loaves x loaves
------------- = ---------------
2.5 hours 7 hours
5 * 7 = 2.5 x
Divide by 2.5
35/2.5 = 2.5x/2.5
14 =x
(a)
421₅ = 4×5² + 2×5¹ + 1×5⁰
… = 100 + 10 + 1
… = 111
(b)
11101₂ = 1×2⁴ + 1×2³ + 1×2² + 0×2¹ + 1×2⁰
… = 16 + 8 + 4 + 0 + 1
… = 29
(c)
13T₁₂ = 1×12² + 3×12¹ + 10×12⁰
… = 144 + 36 + 10
… = 190
Draw one ten, (If you have to draw ones, draw 3 of those) and the new fact is 10 + 3. (That equals 13, if you need that.)
2x+5=47, solve algebraically to find x, the answer
