Answer:
2x + 4
Step-by-step explanation:
Let R = Ralph's age
and x = Sarah's age
Then Ralph's age in 4 years = R + 4
and Sarah's age in four years = x + 4
Thus, R + 4 = 2(x + 4)
Distribute the 2 R + 4 = 2x + 8
Subtract 4 from each side R = 2x + 4
Ralph's age is 2x + 4.
Answer: 60
Step by step: congruent sides
Step-by-step explanation:
1cm = 16 km
Distance between York and London = 23.1 cm
<em>Now the real distance between </em><em>York </em><em>and </em><em>London </em><em>=</em><em> </em><em>2</em><em>3</em><em>.</em><em>1</em><em> </em><em>*</em><em> </em><em>1</em><em>6</em>
<em>=</em><em> </em><em>3</em><em>6</em><em>9</em><em>.</em><em>6</em><em> </em><em>km </em>
